Chemistry
Percentage Yield
Calculate the efficiency of a chemical reaction.
Percentage Yield = (Actual Yield / Theoretical Yield) × 100
Formula Explanation
Actual yield is compared with the maximum theoretical yield predicted by stoichiometry.
Variables Explained
Actual yield = Experimentally obtained product; Theoretical yield = Predicted maximum product.
Solved Example
Actual yield is 8 g and theoretical yield is 10 g.
Percentage yield = (8 / 10) × 100 = 80%.
