    Percent yield = 57%

    Explanation:

    Given dа ta:

    Number of moles of propane = 4.50 mol

    Number of moles of carbon dioxide = 7.64 mol

    Percent yield = ?

    Solution:

    Chemical equation:

    C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

    Now we will compare the moles of propane and carbon dioxide.

    C₃H₈ : CO₂

    1; 3

    4.50 : 3*4.50 = 13.5 mol

    Percent yield:

    Percent yield = actual yield / theoretical yield * 100

    Percent yield = 7.64 mol / 13.5 mol * 100

    Percent yield = 0.57 * 100

    Percent yield = 57%
