In the following experiment, a constant-pressure calorimeter containing 100 ml of H2O is used. The initial temperature of the calorimeter is 24.6oC. If 18.6g of CaCl2is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of solution of CaCl2is -82.8 kJ/mol. The specific heat of water is Cs = 4.18 J g-1 K-1.
