A sample of fructose (C6H12O6) with a mass of 38.5 g is burned in a bomb calorimeter. The heat capacity of this calorimeter had been previously found to be 27.7 kJ/ C. The temperature rose from 25.0 degree Celsius to 46.7 degree Celsius during the combustion. Calculate the heat of combustion of fructose in kJ/gram and kJ/mol.
