When a 0. 235-g sample of benzoic acid is combustion in a bomb calorimeter, the temperature rises 1. 642°c. When a 0. 265-g sample of caffeine, c8h10o2n4, is burned, the temperature rises 1. 525°c. 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.
