Part A
In the following experiment, a coffee-cup calorimeter containing 100 mL of H, 0 is used. The initial temperature of the
calorimeter is 23.0 °C. If 3.50 g of CaCl, is added to the calorimeter, what will be the final temperature of the solution in
the calorimeter? The heat of solution AHoln of CaCl, is -82.8 kJ/mol.
Assume that the specific heat of the solution formed in the calorimeter is the same as that for pure water: C, = 4.184
J/g °C.
Express your answer with the appropriate units.
