A 250 g sample of sucrose C12H22O11(s) was burned in a 21.00 kg iron calorimeter immersed in 1.450 Kg of water. The initial temperature of the system was 24.32 degrees Celsius. Determine the heat of combustion of sucrose under the conditions present inside the calorimeter (CH2O = 4.184 kJ/(kg degrees C) cFe = 0.452 kJ/(kg degrees C)).
