1.8 When $25\mathrm{mL}$ of $1\mathrm{M}{\mathrm{H}}_2{\mathrm{SO}}_4$ is added to $50\mathrm{mL}$ of $1\mathrm{M}\mathrm{NaOH}$ at $25^{?}\mathrm{C}$ in a calorimeter, the temperature of the aqueous solution increases to $33.9^{?}\mathrm{C}$. Assuming that the specific heat of the solution is $4.18\mathrm{J}/\left({\mathrm{g}}^{?}\mathrm{C}\right)$, that its density is $1.00\mathrm{g}/\mathrm{mL}$, and that the calorimeter itself absorbs a negligible amount of heat, Calculate $?\mathrm{H}$ in kilojoules $/\mathrm{mol}{\mathrm{H}}_2{\mathrm{SO}}_4$ for the reaction. ${\mathrm{H}}_2{\mathrm{SO}}_4(\mathrm{aq})+\mathrm{NaOH}(\mathrm{aq})?2{\mathrm{H}}_2\mathrm{O}(l)+{\mathrm{NaSO}}_4(\mathrm{aq})$
