Sucrose is commonly known as table sugar. The formula is C12H22O11. You burn 7.29 grams of sucrose in a bomb calorimeter. The temperature of the calorimeter and the water in it rises from 23.24 degrees celsius to 29.77 degrees celsius. The bomb's heat capacity had been determined to be 6.35 kJ/degrees celsius. There is 1400 grams of water in the calorimeter. Find the heat of combustion of sucrose in both kJ/gram and kJ/mole.
