In the following experiment, a coffee-cup calorimeter containing 100 mL of H20 is used. The initial temperature of the calorimeter is 23.0 C . If 3.60 g of CaCl2is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of the change in enthalpy (H)soln solution of CaCl2 is -82.8kJ/mol.
The specific heat of H2O is 4.18 kJ/g or 75.24 kJ/mol
