In the following experiment, a coffee-cup calorimeter containing 100mL of H2O is used. The initial temperature of the calorimeter is 23.0C. If 5.70g of CaCl2 is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of solution Hsoln of CaCl2 is 82.8kJ/mol. Assume that the specific heat of the solution formed in the calorimeter is the same as that for pure water: Cs=4.184 J/gC. Express your answer with the appropriate units
