Choose a calculation for density p, mass m or Volume V. Enter the other two values and the calculator will solve for the third in the selected units. You can also enter scientific notation such as 3.45e22.
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume. Along with values, enter the known units of measure for each and this calculator will convert among units.
The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value. It is useful to carefully write out whatever values are being worked with, including units, and perform dimensional analysis to ensure that the final result has units of massvolume. Note that density is also affected by pressure and temperature. In the case of solids and liquids, the change in density is typically low. However, when regarding gases, density is largely affected by temperature and pressure. An increase in pressure decreases volume, and always increases density. Increases in temperature tend to decrease density since the volume will generally increase. There are exceptions however, such as water's density increasing between 0C and 4C.
Molecular mass is the mass of a single molecule of a compound. It can be calculated by summing the atomic masses of each nuclide present in the molecule and is measured in Daltons (Da or u). The atomic mass of all the known chemical elements can be found in the periodic table. For a bulk of molecules, such as a pure chemical compound supplied by Tocris, molecular weight refers to a weighted average of the molecules in the compound.
In practice, it is very difficult to accurately measure molecular weight of a compound. Molar mass and formula weight are commonly used as numerical approximations for molecular weight. Molar mass is the mass of a substance containing 1 mol of molecules; it has the unit of g/mol. The molar mass of a compound with a given chemical formula can be calculated as the sum of the atomic weights of all atoms appearing in the formula and this number is also known as the formula weight of the compound.
In general, the molecular mass, molecular weight, molar mass, or formula weight of a chemical compound can be used when using a molarity or concentration calculator for preparing a solution. In biochemistry, Daltons and g/mol (gram per mole) can be used interchangeably i.e. 1 Dalton = 1 g/mol.
Molar concentration (also known as molarity) is the amount of a solute (in moles) per unit volume of solution. It is denoted by the unit M, and 1 M = 1 mol/L. Please see the example above for how to use the Tocris molarity calculator to calculate the molarity of a solution.
The molarity calculator calculates the mass of compound required to achieve a specific molar concentration and volume. To dilute a solution of known molarity, please use the Solution Dilution Calculator. To dilute a solution of concentrated acid or base of known w/w% strength, please use the Acid & Base Molarity Calculator.

Density is a measure of how much mass is contained in a given volume. It describes how tightly packed the particles or molecules of a substance are. Understanding density is important because it helps us explain various phenomena in the physical world, such aswhy some objects float while others sink, why ice is less dense than liquid water, and why hot air rises.
The density of a material is scientifically defined as its mass per volume. It can also be thought of as how compacted or compressed asubstance is. When calculating a density from a mass and volume figure, it's important to remember that density can be affected by pressure andtemperature, particularly where gases are concerned.
It's a common request that people want to know how they can convert a volume to a weight, hoping it's a simple one-to-one conversion. And it's for that reasonthat I built my weight to volume converter and cooking calculatortools. So, please do make use of those tools if you need to.
As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
The concentration calculator allows you to quickly calculate the volume, mass or concentration of your vial. Simply enter your mass, volume, or concentration values for your reagent and the calculator will determine the rest.
Two solutions that have the same molarity will have the same number of molecules of the chemical per liter but are likely to contain differing masses of that chemical per liter to achieve this. Whereas two solutions at the same concentration will have the same mass of the chemical per liter of solution but are therefore likely to have differing numbers of molecules of that chemical per liter. Provided some additional information is known, one value can be deduced from the other using the equations below.

At Stargate Hydrogen we think of every detail to help your industry to reduce carbon emissions by adopting green hydrogen. That is why we created the Hydrogen calculators. Here you can calculate the mass of hydrogen, convert between hydrogen mass and volume, or convert between hydrogen mass and the energy content.
An object's density is represented by a ratio of its mass to volume. The units, used for measurements are, therefore, mass per unit volume.Mass, if we look from a physicist's perspective, can be defined as a measure of the quantity that is inside a body, excluding such factors as the volume of an object or any forces that might be acting on the object.Volume represents the amount of space that is occupied by an object in three dimensions.How to use this calculator: Enter any two known values to calculate the third one.Mass, Density, Volume CalculatorMass (m):mggkgozlbDensity (ρ):mg/Lg/Lkg/Lkg/mlb/ftoz/inoz/ftlb/inVolume (V):mlLcmminftyd
As stated previously, chemists have defined several types of concentrations, which each use a different chemically-acceptable unit, or combination of units, to indicate the amount of solute that is dissolved in a given amount of solvent. The following paragraphs will present and apply the equation that is used to calculate a mass/volume percent, which is the final type of percent-based concentration that will be discussed in this chapter.
The mass/volume percent of a solution is defined as the ratio of the mass of solute that is present in a solution, relative to the volume of the solution, as a whole. Because this type of concentration is expressed as a percentage, the indicated proportion must be multiplied by 100, as shown below.
As discussed in the previous two sections of this chapter, mass percents and volume percents can be calculated using an alternative equation, in which the masses or volumes, respectively, of the solute and the solvent that are contained in a solution are added to obtain the mass or volume, respectively, of that solution, as a whole. While mass percents are typically reported for solid- and liquid-phase solutions, and volume percents are usually determined for liquid- and gas-phase solutions, a mass/volume percent concentration is most often calculated for solutions that are specifically prepared by dissolving solid solutes in liquid solvents. In order to create this type of solution, the solid solute particles must overcome the attractive forces that exist between the liquid solvent molecules, in order to move throughout and occupy the "empty" spaces that are temporarily created during the solvation process. After the solute particles have dispersed throughout the solvent, the solvent molecules interact more strongly with the solvated solute particles than with other solvent molecules and, consequently, exist in closer physical proximity to those solute particles, relative to other solvent molecules. As a result of these solute-solvent interactions, the solvated solute particles occupy less space than they had prior to their solvation, which causes the volume of the solution, as a whole, to decrease, relative to the combined volumes of the individual solute and solvent. Because the magnitude of this volumetric contraction varies based on the solute and solvent that are utilized to prepare a solution, calculating the mass/volume percent of a solution by adding the volumes of its components is prohibitively challenging. Therefore, only the equation that is shown above can be applied to reliably determine the mass/volume percent of a solution.
In order to be incorporated into the equation that is shown above, the mass of the solute must be expressed in grams, the volume of the solution must be provided in milliliters, and the chemical formula of each component must be written as the secondary unit on its associated numerical quantity. Therefore, if either of these measurements is reported using an alternative unit, its value would need to be converted to the appropriate unit prior to being incorporated into the mass/volume percent equation.
During the multiplication and division processes that are used to solve this equation, no unit cancelation occurs, because the units that are present in the numerator and denominator, "g" and "mL," respectively, do not match one another. Therefore, the unit that results from the division of the indicated quantities is "g/mL," which is a unit that is typically utilized to report the density of a substance. Because densities and mass/volume percent concentrations have unique definitions and are calculated using different equations, these measurements are distinctive quantities and, consequently, cannot be expressed using the same unit. Therefore, the mass and volume units are eliminated during the simplification of the mass/volume percent equation, even though "g" and "mL" do not cancel, mathematically, and the calculated concentration is expressed as a percentage. However, as stated previously, the quantity of solute that is present in a given solution can be expressed using three unique percent-based concentrations. In order to distinguish a mass/volume percent, which is calculated by simplifying a mass-to-volume ratio, from the other percent-based concentrations, the unit in which a mass/volume percent concentration is reported is "% m/v," and the chemical formula of the solute is written as the secondary unit on this calculated quantity.
