500 mL of .200 M HCl (aq) was added to a high quality insulated calorimeter containing 500.0 mL of .237 M NaOH (aq). The mixture of solutions has a density of 1.220 g/mL and a specific heat of 5.254 J/gC. The empty calorimeter had a heat capacity of 850.0 J/C. The temperature of the entire system rose from 25.6 C to 26.7 C. Calculate the heat of the reaction, in kJ per mole of HCl that reacted.
