JEE MainChemistryThermodynamicsNumerical+4 / −1
A sample of n -octane (1.14 g)(1.14 \mathrm{~g})(1.14 g) was completely burnt in excess of oxygen in a bomb calorimeter, whose heat capacity is 5 kJ K−15 \mathrm{~kJ} \mathrm{~K}^{-1}5 kJ K−1. As a result of combustion reaction, the temperature of the calorimeter is increased by 5 K . The magnitude of the heat of combustion of octane at constant volume is ‾kJmol−1\underline{\hspace{2cm}}\mathrm{kJ} \mathrm{mol}^{-1}​kJmol−1 (nearest integer).
