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 0.6334 g sample of acetylsalicylic acid (C9H8O4) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.100×103 g of water. During the combustion the temperature increases from 22.68 to 25.23 °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 929.9 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of acetylsalicylic acid based on these data.
