A chemical engineer studying the properties of fuels placed2.366 g of a hydrocarbon in the bomb of a calorimeter and filled it with O2gas. The bomb was immersed in 2.723 L of water and the reaction was initiated. The water temperature rose from13.46 °C to 31.27 °C. If the calorimeter (excluding thewater) had a heat capacity of 420. J/K, what was the heat of combustion of the fuel?
