Thermodynamics

The enthalpy of combustion of propane, graphite and dihydrogen at \(298 \mathrm{~K}\) are \(-2220.0 \mathrm{~kJ} \mathrm{~mol}^{-1},-393.5 \mathrm{~kJ} \mathrm{~mol}^{-1}\) and \(-285.8 \mathrm{~kJ} \mathrm{~mol}^{-1}\) respectively. The magnitude of enthalpy of formation of propane \(\left(\mathrm{C}_{3} \mathrm{H}_{8}\right)\) is _______________ \(\mathrm{kJ} \,\mathrm{mol}^{-1}\). (Nearest integer)
