can u help me with this problem i dont understand the equation and how to use the equations

5. The mean bond enthalpies of CC,CH,C=O, and OH bonds are 348,412,743, and 463kJ/mol, respectively. The combustion of a fuel such as octane is exothermic because relatively weak bonds break to form relatively strong bonds. Use this information to justify why glucose has a lower specific enthalpy than lipid decanoic acid (C10H2O2) even though these compounds have similar molar masses
