A sample of n-octane \((1.14\mathrm{g})\) was completely burnt in excess of oxygen in a bomb calorimeter, whose heat capacity is \(5\mathrm{kJ}{\mathrm{K}}^{-1}\). As a result of combustion reaction, the temperature of the calorimeter is increased by \(5\mathrm{K}\) . The magnitude of the heat of combustion of octane at constant volume is _____ \({\mathrm{kJmol}}^{-1}\) (nearest integer).
