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