Does anyone have a table of solution enthalpy values that shows the
standard value of Epsom salt - Magnesium sulfate heptahydrate?

Thanks much

Standard enthalpy of formation of MgSO4.7H2O at 298.15K is -3388.71 kJ/mol,
according to Wagman et al., *The NBS Tables of chemical thermodynamic
properties....*, p. 2-263. (These Tables were published in 1982; the datum
cited may be much older.)

IHTH.
