A quantity of 85.0 mL of 0.900 M HCl is mixed with 85.0 mL of 0.900 M KOH in a constant-pressure calorimeter that has a heat capacity of 325 J/C. If the initial temperatures of both solutions are the same at 18.24C, what is the final temperature of the mixed solution? The heat of neutralisation is -56.2 kJ/mol. Assume the density and specific heat of the solutions to be the same as those of water.
