A reaction has a theoretical yield of 50 g and an actual yield of 30 g. Calculate the percentage yield.

A reaction has a theoretical yield of 50 g and an actual yield of 30 g. Calculate the percentage yield.

• A. 30%
• B. 60%
• C. 50%
• D. 40%

Answer: (B)

Percentage yield shows how much product you actually get compared with what’s theoretically possible, expressed as a percentage. It’s calculated by dividing the actual yield by the theoretical yield and multiplying by 100. Here, the actual yield is 30 g and the theoretical yield is 50 g. 30 ÷ 50 = 0.6, and 0.6 × 100 = 60%. So the percentage yield is 60%.
