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 0.7090 g sample of adipic acid (C6H1004) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.201×10° g of water. During the combustion the temperature increases from 22.33 to 24.58 °C. The heat capacity of water is 4.184 J gloc!. The heat capacity of the calorimeter was determined in a previous experiment to be 799.0 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of adipic acid based on these data.
