A 1.0g sample of an unknown salt (molar mass = 40 g/mol) is added to 75.0mL of water. The temperature of the water rises 32oC after the salt is added, what is the molar heat of solution for the salt? Assume the density of water is 1.00g/mL throughout this experiment and that the calorimeter constant is 5J/oC.

a. -10.2 kJ/mol
b. -407 kJ/mol
