Question

I have this question and I am pretty sure on what to use to solve it but I am just stuck. The reaction of 8 g of hydrogen and 28 g of carbon monoxide gave 16 g of methanol. What was the theoretical yield if the percent yield was 50%?

actual yield
________________ X 100% = percent yield
theoretical yield

Any help or explantion of the process would be greatly appreciated.

Answer 1

(Actual/theoretical)*100 = 50
(A/T) = 50/100 = 0.50
A = 0.5T or
T = A/0.5 = 2A
Theo = 2*16(from the problem) = 32 g.
