Problem

Aqueous hydrochloric acid and sodium hydroxide react according to HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)\mathrm{HCl(aq)+NaOH(aq)\to NaCl(aq)+H_2O(l)} with ΔHrxn=−57.3 kJ\Delta H_{\text{rxn}}=-57.3\,\text{kJ} per mole of H2O\mathrm{H_2O} formed. If 500. mL500.\,\text{mL} of 1.50 M1.50\,\text{M} HCl\mathrm{HCl} is mixed with 200. mL200.\,\text{mL} of 3.00 M3.00\,\text{M} NaOH\mathrm{NaOH}, calculate the heat released by the neutralization.
