Abomb 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 1.1070 g sample of fumaric acid (c4h4o4) is burned completely in a bomb calorimeter. the calorimeter is surrounded by 1.093ă—103 g of water. during the combustion the temperature increases from 22.10 to 24.52 â°c. the heat capacity of water is 4.184 j g-1â°c-1. the heat capacity of the calorimeter was determined in a previous experiment to be 891.1 j/â°c. assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of fumaric acid based on these data. c4h4o4(s) + 3o2(g) 2 h2o(l) + 4 co2(g) + energy
