When a 0.245-gg sample of benzoic acid is combusted in a bomb calorimeter, the temperature rises 1.641 oCoC. When a 0.275-gg sample of caffeine, C8H1002N4C8H1002N4, is burned, the temperature rises 1.517 oCoC. Using the value 26.38 kJ/gkJ/g for the heat of combustion of benzoic acid, calculate the heat of combustion per mole of caffeine at constant volume.
