The enthalpy of combustion of benzoic acid (C6H5COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be 3226.7 kj?mol. when 2.9683 g of benzoic acid are burned in a calorimeter, the temperature rises from 21.84 C to 24.67 C. What is the heat capacity of the bomb? (Assume that the quantity of water surrounding the bomb is exactly 2250 g.)
