The combustion of 0.1568 g of benzoic acid increases the temperature of a bomb calorimeter by 2.57°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 0.2105 g sample of vanillin (C8H8O3) is then burned in the same calorimeter, and the temperature increases by 3.29°C. What is the energy of combustion per gram of vanillin? Energy = _______ kJ/g Per mole of vanillin? Energy = ______ kJ/mol

The combustion of 0.1584 g benzoic acid increases the temperature of a bomb calorimeter by $2.54^{\circ} \mathrm{C}$ . Calculate the heat capacity of this calorimeter. (The energy released by combustion of benzoic acid is 26.42 $\mathrm{kJ} / \mathrm{g} .$ ) A $0.2130-\mathrm{g}$ sample of vanillin $\left(\mathrm{C}_{8} \mathrm{H}_{8} \mathrm{O}_{3}\right)$ is then burned in the same calorimeter, and the temperature increases by $3.25^{\circ} \mathrm{C}$ . What is the energy of combustion per gram of vanillin? Per mole of vanillin?
