Question

If 9.87g of As2O3 reacts with carbon, then 7.71g of As should be produced. If only 6.33g of As is actually produced, what is the percent yield of As?

a 82.1%
b 0.821%
c 64.1%
d 0.641 %

Answer 1

82.1%

Step-by-step explanation:

A. I got it right on my test

Answer 2

A

Step-by-step explanation:

Percent yield= Actual yield/Theoretical yield x 100

The problem tells you that 6.33g of As is produced (actual yield), but 7.71g should be produced (theoretical yield). So 6.33/7.71= 0.821 x 100= 82.1%
