When $\displaystyle 5$ litres of a gas mixture of methane and propane is perfectly combusted at $\displaystyle 0$°C and $\displaystyle 1$ atmosphere, $\displaystyle 16$ litres of oxygen at the same temperature and pressure is consumed. The amount of heat released from this combustion in kJ $\displaystyle \left(\Delta \mathrm{H}_{\text {comb. }}\left(\mathrm{CH}_4\right)=890 \mathrm{~kJ} \mathrm{~mol}^{-1}, \Delta \mathrm{H}_{\text {comb. }}\left(\mathrm{C}_3 \mathrm{H}_8\right)\right.$ $\displaystyle =2220 \mathrm{~kJ} \mathrm{~mol}^{-1}$ ) is :
