A chemical engineer studying the properties of fuels placed 1.475 g of a hydrocarbon in the bomb of a calorimeter and filled it with O2 gas. The bomb was immersed in 2.407 L of water and the reaction initiated. The water temperature rose from 21.20C to 23.15C. If the calorimeter (excluding the water) had a heat capacity of 403 J/K, what was the heat of combustion (qv) per gram of the fuel?
