  1. 2CH4 + 4Cl2 = 2CCl4 + 4H2
    the theoretical yield is 2 moles of CCl4, or 154g
    You got 117g, or 117/154 = 76%

  2. CH4 + 4Cl2 → CCl4 + 4HCl
    2 mols CH4 will produce 2 mols CCl4.
    2 mols CCl4 has a mass of 2*[12 + 4*35.5] = 308 g.That is the theoretical yield.
    actual yield = 117 grams = AY
    theoretical yield = 308 grams = TY
    %yield = (AY/TY)*100 = ?

  3. @oobleck. 2 mol CCl4 = 2*154 = 308 g

  5. We should outlaw all coefficients.
