Chapter , Problem 5.101a(choose chapter or problem)
(a) When a 0.235-g sample of benzoic acid is combusted in a bomb calorimeter (Figure 5.18), 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
