In the following experiment, a coffee-cup calorimeter containing 100 mL.of H2O is used. The initial temperature of the calorimeter is 23 degree C If 4.10 g of CaCl2 is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of solution Delta H soln of CaCl2 is -* 82.8 kJ/mol. Assume the density of solution is 1 g/mL. Note: Here Heat of solution Delta H soln is refering to the enthalpy change for dissolving 1 mol of CaCI2(s) in water, or the following process: CaCI2(s) rightarrow CaCI2(aq) Delta H = - 82.8 kJ
