2CH4 + 4Cl2 = 2CCl4 + 4H2
the theoretical yield is 2 moles of CCl4, or 154g
You got 117g, or 117/154 = 76%
In a reaction 2 moles of CH4 were reacted with an excess of Cl2. As a result 117gram of CCl4 is obtained. What is theoratical yield?
Actual yield?
%age yield?

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 = ?

@oobleck. 2 mol CCl4 = 2*154 = 308 g
dang those pesky coefficients!
We should outlaw all coefficients.
