A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.6158 g sample of benzoic acid (C₂H6O2) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.148x10³ g of water. During the combustion the temperature increases from 27.72 to 30.66 °C. The heat capacity of water is 4.184 J g-¹°C-¹. The heat capacity of the calorimeter was determined in a previous experiment to be 902.7 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of benzoic acid based on these data.
