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 0.5021 g sample of heptadecanoic acid (C,,H,0,) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.246x10 g of water. During the combustion the temperature increases from 21.91 to 25.07 °C. The heat capacity of water is 4.184 Jg1°C1. tin The heat capacity of the calorimeter was determined in a previous experiment to be 822.9 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of heptadecanoic acid based on these data.
