If theoretical yield is 52.0 g and actual yield is 36.0 g, what is the percent yield?

• A. 66.7%
• B. 69.23%
• C. 72.0%
• D. 50.0%

Answer: (B)

Percent yield measures how much product you actually obtained compared with how much could theoretically be produced, expressed as a percent. It is found by dividing the actual yield by the theoretical yield and multiplying by 100. With a theoretical yield of 52.0 g and an actual yield of 36.0 g, 36.0 ÷ 52.0 = 0.692307, and multiplying by 100 gives 69.23%. This matches the correct option. Rounding to two decimal places is common, as shown.
