Question- 500.0 mL of 0.100 mol L-1 HCl(aq) was added to a high quality insulated calorimeter containing 500.0 mL of 0.100 mol L-1 NaOH(aq). Both solutions had a density of 1.000 g mL-1 and a specific heat of 4.184 J g-1 K-1. The calorimeter had a heat capacity of 850.0 J K-1. The temperature of the entire system rose from 25.50 oC to 26.05 oC. Calculate ?H in kJ per mole of NaOH.
Enter your answer in kJ mol-1 to one decimal place. Please comprise units as well
