The standard enthalpy of combustion of sucrose is -5645 kJ mol ${}^{-1}$. What is the advantage (in $\mathrm{kJ}{\mathrm{mol}}^{-1}$ of energy released as heat) of complete aerobic oxidation compared to anaerobic hydrolysis of sucrose to lactic acid ? $\Delta {\mathrm{H}}_{\mathrm{f}}{}^{\circ }$ for lactic acid, ${\mathrm{CO}}_2$ and ${\mathrm{H}}_2\mathrm{O}$ is -694, -395.0 and -286.0 respectively.
