The combustion of 0.1593 g benzoic acid increases the temperature of a bomb calorimeter by 2.55°C. Calculate the heat capacity of this calorimeter. (The energy released by combustion of benzoic acid is 26.42 kJ/g.) Heat capacity = kJ/°C A 0.2160-g sample of vanillin (Cg Hs O3) is then burned in the same calorimeter, and the temperature increases by 3.26°C. What is the energy of combustion per gram of vanillin? Energy = kJ/g Per mole of vanillin? Energy = kJ/mol
