7. A 2.053-g sample of ethylene glycol, CH.02 (62.07 g/mol) was burned in a bomb calorimeter with excess oxygen. The temperature of the calorimeter and the water before combustion was 16.49 °C; after combustion the calorimeter and the water had a temperature of 23.12 °C. The calorimeter had a heat capacity of 567 J/K, and contained 1.316 kg of water. Use these data to calculate the molar heat of combustion (in kJ) of ethylene glycol.
