a) A calorimeter was calibrated with an electric heater, which supplied 22.5 kJ of energy as heat to the calorimeter and its water bath from 22.45OC to 23.97OC. What is the heat capacity of the calorimeter?
(b) The enthalpy of combustion of benzoic acid, C6H5COOH, which is often used to calibrate calorimeters, is −3227 kJ/mol. When 1.453 g of benzoic acid was burned in a calorimeter, the temperature increased by 2.265OC. What is the heat capacity of the calorimeter?
