  1. Mg + Cl2 -> MgCl2
    5.00 g Mg / 24 g/mol / 1 (from balanced equation) = 0.21

    10.0 g Cl2 / 71 g/mol / 2 (from balanced equation) = 0.070

    Smallest number is limiting reactant = Cl2

    Yield = 10.0 g Cl2 / 71g/mol X 1 mol MgCl2/1 mol Cl2 X 95 g MgCl2/mol = 13.4 g

  2. 10 g Cl2 / 71 g/mol /1 (balanced equation) = 0.141

    Still the limiting reactant\
    MgCl2 is still 13.4

    Sorry!
