Can you please help me find the answer with solution? Thank you very much?

For the balanced equation shown below, if the reaction of 13.4 grams of C2H5Cl produces 5.76 grams of Cl2, what is the percent yield?

4C2H5Cl + 13O2 => 8CO2 + 10H2O + 2Cl2

    Molar mass of C2H5Cl is 64.51 g/mol.

    Molar mass of Cl2 is 70.906 g/mol.

    The 13.4 g of C2H5Cl is 13.4/64.51 moles = 207.7 millimoles.

    The 5.76 g of Cl2 is 81.2 millimoles.

    But each mole of C2H5Cl should produce 0.5 moles of Cl2,

    so the 207.7 millimoles of C2H5Cl should produce 103.85 millimoles of Cl2.

    The percent yield is 81.2/103.85 = 78.2%.

    Look up the atomic masses of these elements to calculate the number of moles in 13.4 g of C2H5Cl and 5.76 g of Cl2.

    Use the reaction formula to calculate how many moles of Cl2 could have been produced from that starting amount of C2H5Cl.

    Thus, what is the percent yield of the reaction that only yielded 5.76 g?
