A 150.0 mL sample of a 1.50 M solution of CuSO4
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/K.
Calculate the ΔHrxn for this reaction in units of kJ / mol of copper (II) hydroxide.Assume
the solutions is dilute enough that the specific heat and density of the solution is the same as that
of water
