Percentage Yield Calculator





Formula

The formula to calculate Percentage Yield (Y) is:

\[ Y = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100 \]

What is Percentage Yield?

Percentage Yield (or percent yield) is a measure of the efficiency of a chemical reaction. It indicates the ratio of the actual yield to the theoretical yield, expressed as a percentage. A high percentage yield indicates that a reaction is efficient and producing a high proportion of the expected product.

Example Calculation

Suppose the Actual Yield (AY) of a reaction is 85 grams and the Theoretical Yield (TY) is 100 grams.

To calculate the Percentage Yield:

\[ Y = \left( \frac{85}{100} \right) \times 100 = 85\% \]

Therefore, the Percentage Yield is 85%.
