A 150.0 mL sample of a 1.50 M solution of CuSO_{4} is mixed with a 150.0 mL sample of 3.00 M KOH in a coffee cup calorimeter. The temperature of both solutions and the calorimeter was 25.2 C before mixing and 31.3 C after mixing. The heat capacity of the calorimeter is 24.2 J/C. Calculate the H_{rxn} for this reaction in units of kJ/mol of copper(II)hydroxide. Assume the solution is dilute enough that the specific heat and density of the of the solution is the same as that of water.
