A light fuel oil with an average chemical composition of C10H18 is burned with oxygen in a bomb calorimeter. The heat evolved is measured as 43,960 Jg1 for the reaction at 25C. Calculate the standard heat of combustion of the fuel oil at 25C with H2O(g) and CO2(g) as products. Note that the reaction in the bomb occurs at constant volume, produces liquid water as a product, and goes to completion. The molar mass of C10H18 is 162.27 gmol1. The standard heat of combustion is ___ Jmol1.
