Calculate the heat capacity of the calorimeter:
When a 0.240-g sample of benzoic acid is combusted in a bomb calorimeter, the temperature rises 1.643 oC . When a 0.270-g sample of caffeine, C8H10O2N4, is burned, the temperature rises 1.523 oC . Using the value 26.38 kJ/g for the heat of combustion of benzoic acid, calculate the heat of combustion per mole of caffeine at constant volume.
