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. The temperature of both solutions was 23.5 degrees (C) before mixing and 31.0 degrees(C) after mixing. The heat capacity of the calorimeter is 12.1 J/K. From these data, calculate ΔH for the process: CuSO4(1M)+ 2KOH(2M) →Cu(OH)2(s) + K2SO4(0.5M) Assume that the specific heat and density of the solution after mixing are the same as those of pure water and that the volumes are additive.
