In a reaction, the theoretical yield of a product is 25.0 grams. If the actual yield of the product is 20.0 grams, what is the percentage yield?
Understand the Problem
The question is asking to calculate the percentage yield of a chemical reaction, given the theoretical yield and the actual yield. The percentage yield is calculated by dividing the actual yield by the theoretical yield, and then multiplying by 100%.
Answer
80%
The percent yield is 80%.
Answer for screen readers
The percent yield is 80%.
More Information
Percent yield is calculated by dividing the actual yield by the theoretical yield, then multiplying by 100%. In this case, (20.0 grams / 25.0 grams) * 100% = 80%.
Tips
A common mistake is dividing the theoretical yield by the actual yield. Always divide the actual yield by the theoretical yield to get the correct percentage.
