The enthalpy of combustion of benzoic acid $\left({\mathrm{C}}_6{\mathrm{H}}_5\mathrm{COOH}\right)$ is commonly used as the standard for calbrating constant-volume bomb calorimeters; its value has been accurately determined to be $-3226.7\frac{\mathrm{kJ}}{\mathrm{mol}}$. When $2.6409\mathrm{g}$ of benzolc acld are bumed in a calorimeter, the temperature rises from $21.84{}^{\circ }\mathrm{C}$ to $26.677^{\circ }\mathrm{C}$. What is the heat capscity of the bomb? (Assume that the quantity of water surrounding the bomb is exactly 2250 g.) Round vour answer to 3 significant digits.
