I can't figure out where I'm going wrong on this question. Any help is much appreciated: A chemical engineer studying the properties of fuels placed 1.500 g of a hydrocarbon in the bomb of a calorimeter and filled it with oxygen gas. The bomb was immersed in 2.500 L of water (assume the density of water is 1.000g/mL) and the reaction initiated. The water temperature rose from 20.00 degrees C to 23.55 degrees C. If the calorimeter (excluding the water) had a heat capacity of 403 J/degree C, calculate the
heat of combustion per gram of the fuel.
