A 1.764-g sample of heptanoic acid, C7H14O2 (130.19 g/mol) was burned in a bomb calorimeter with excess oxygen. The temperature of the calorimeter and the water before combustion was 23.68 °C; after combustion the calorimeter and the water had a temperature of 32.12 °C. The calorimeter had a heat capacity of 500 J/K, and contained 1.462 kg of water. Use these data to calculate the molar heat of combustion (in kJ) of heptanoic acid.

A 1.9862-g sample of benzoic acid burns in an excess of oxygen, in a bomb calorimeter. The temperature of the calorimeter rises from 24.94 C to 28.77 C. The calorimeter contains 2000.0 g of H2O, and the heat capacity of the calorimeter (excluding the water, but including the bomb, thermometer, and all mechanical parts) has the value C(cal) = 5.35 kJ/C. Use the given information to find the molar heat of combustion of benzoic acid (M(benzoic acid) = 122.1 g/mol).
