A 1.615-g sample of benzoic acid, C7H6O2 (122.12 g/mol) was burned in a bomb calorimeter with excessoxygen. The temperature of the calorimeter and the water before combustion was 17.49 °C; after combustionthe calorimeter and the water had a temperature of 27.28 °C. The calorimeter had a heat capacity of 832 J/K,and contained 0.837 kg of water. Use these data to calculate the molar heat of combustion (in kJ) of benzoicacid.

Fructose, C6H12O6(s), is a sugar closely related to glucose.. A 0.755 g sample of fructose was combusted with excess oxygen in a bomb calorimeter, containing 500.0 g of water. The heat capacity of the empty calorimeter was 208 J/K.
