7.5 g of a solid are added to 87.6g of water at 23.7 degrees C. When the solid has all been dissolved and thoroughly mixed with the water, the temperature of the solution is decreased by 6.2 degrees C.
Calculate the heat of the solution in joules per gram of the solid.

qH2O = mass water x specific heat water x (Tfinal-Tinitial).
Then q/7.5 = heat of solid/gram if you use specific heat of water in joules (4.18 joules/g*C). Note that they tell you Tfinal-Tinitial = 6.2 degrees.
