    Answer: 8 moles

    Explanation:

    C3H8 (g) + 5O2 (g) - --> 3CO2 (g) + 4H2O (g)

    The balanced equation above shows the combustion of propane, C3H8 (for x is 3; y is 8) in oxygen, O2 to yield carbon dioxide, CO2 and water, H2O

    The mole ratio on combustion are as follows:

    5 moles of O2 react to produce 3 moles of CO2

    Z mole of O2 react to produce 4.8 moles of CO2

    To get the value of Z, cross multiply

    4.8 moles x 5 mole = 3 mole x Z

    24 = 3Z

    Divide both sides by 3

    24/3 = 3Z/3

    8 = Z

    Thus, in the combustion of propane, 8 moles of oxygen (O2) are needed to react to produce 4.8 moles of carbon dioxide (CO2)
