In the following experiment, a coffee-cup calorimeter containing 100 mLmL of H2OH2O is used. The initial temperature of the calorimeter is 23.0 ∘C∘C . If 2.10 gg of CaCl2CaCl2 is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of solution ΔHsolnΔHsoln of CaCl2CaCl2 is −82.8 kJ/mol−82.8 kJ/mol. Assume that the specific heat of the solution formed in the calorimeter is the same as that for pure water: Cs=4.184Cs=4.184 J/g⋅∘CJ/g⋅∘C. Express your answer with the appropriate units.
