A dilute solution of hydrochloric acid with a mass of 610.29 g and containing 0.33183 mol of HCl was exactly neutralized in a calorimeter by the sodium hydroxide in 615.31 g of a dilute NaOH solution. The temperature increased from 16.784 to 20.610 °C. The specific heat of the HCl solution was 4.031 J g-1 °C-1; that of the NaOH solution was 4.046 J g-1 °C-1. The heat capacity of the calorimeter was 77.99 J °C-1. Use these data to calculate the heat evolved by the following reaction.
HCl(aq) + NaOH(aq) --> NaCl(aq) + H2O(l)
What is the heat of neutralization per mole of HCl? Assume that the original solutions made independent contributions to the total heat capacity of the system following their mixing.
