Heat of solution

Homework Statement

What is the heat of solution of calcium chloride (CaCl2) and sodium bicarbonate (NaHCO3)?

The Attempt at a Solution

Heat of solution is more formally known as the enthalpy of fusion. I tried googling this but I am not sure if this is the correct answer...
Heat of solution of CaCl2: -81.3 kJ/mol
Heat of solution of NaHCO3: +33 kJ/mol

Any help is appreciated! Any websites with such information would be awesome!
