Sample problem:

In a calorimeter, completely neutralize $100mL$ of an aqueous solution of sodium hydroxide $(NaOH)$ at $0\mathrm{.}5mo\frac{l}{L}$ by adding $100mL$ of a hydrochloric acid $(HCl)$ solution at $0\mathrm{.}5mo\frac{l}{L}.$ The initial temperature of the solutions before being mixed is $22\mathrm{.}5C.$ The highest temperature obtained during the neutralization, after the two solutions are mixed, is $25\mathrm{.}9C.$ Calculate the molar heat of neutralization of sodium hydroxide.
