A volume of 600.0 mL of 0.240 M perchloric acid, HClO4(aq) was added to a high quality constant-pressure calorimeter containing 400.0 mL of 0.300 M KOH(aq). Both solutions have a density of 1.000 g mL-1 and a specific heat of 4.184 J g-1 °C-1. The calorimeter had a heat capacity of 950.0 J °C-1. The temperature of the entire system rose from 25.30 °C to 26.59 °C. Calculate the heat of reaction, in kJ, per mole of KOH(aq).
