    2. Relevant equations

    You must find or know the formula for octane. Write a balanced reaction for the burning of octane. Your reactants are octane and oxygen.



    3. The attempt at a solution

    The ratio of CO2 to octane comes from your balanced reaction. This is used in determing the amount of CO2 product.

    A intuitive solution is to find the number of moles of C in 40 moles of octane. Octane has 8 C in a molecule.

    Considering that Co2 has one C that means that the end result is ... very clear.

    I presume you mean when 40 moles of octane are completeley combusted;

    Octane + Oxygen --> CO2 + Water
