In an experiment, a 0.4486 g sample of 1,9-nonanediol (C9H20O2) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.284×103 g of water. During the combustion the temperature increases from 26.63 to 29.14 °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 823.6 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of 1,9-nonanediol based on these data. C9H20O2(s) + 13O2(g)-----> 10 H2O(l) + 9 CO2(g) + Energy Molar Heat of Combustion = kJ/mol
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.
