A 50.0 mL sample of a 1.00 M solution of CuSO4 is mixed with 50.0 mL of 2.00 M KOH in a calorimeter. CuSO4 (1M) + 2KOH (2M) Cu(OH)2 (s) + K2SO4 (0.5M). The temperature of both solutions was 20.2 °C before mixing and 26.3 °C after mixing. The heat capacity of the calorimeter is 12.1 J/°C. Assume the specific heat and density of the solution after mixing are the same as those of pure water. From this data, calculate the ΔH for the process if there is 0.05 mols of CuSO4. (Energy of the water + Energy of the calorimeter)/(1000 x mol)= kJ/mol of reaction)
