Percent yield question

Question

A reaction is calculated to make 80.0 g of a product. If 60.0 g are made, what is the percent yield?

Answer 1

Percent yield is equal to (actual mass produced / calculated mass produced) x 100%.

In this case, the actual mass produced was 60 g, and the calculated mass to be produced was 80 g.

60/80 = 6/8 = 3/4, which is .75 in decimal form. Now we multiply that by 100%: .75 x 100% = 75%. Therefore, the percent yield in this experiment was 75%.
