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 0.4750 g sample of tridecanedioic acid (C13H2404) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.121x103 g of water. During the combustion the temperature increases from 22.02 to 24.50 °C. The heat capacity of water is 4.184 ) g-¹°C-¹. The heat capacity of the calorimeter was determined in a previous experiment to be 931.4 1/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of tridecanedioic acid based on these data.
