The percent yield of a chemical reaction is the actual yield divided by the theoretical yield, multiplied by 100:
percent yield = (actual yield / theoretical yield) × 100%
- Theoretical yield is the maximum amount of product predicted by stoichiometry (assuming complete conversion of the limiting reagent).
- Actual yield is the amount of product actually obtained from the experiment.
Percent yields are usually between 0% and 100%; values above 100% indicate experimental error (e.g., impure product, incomplete drying, or measurement error).
Example: if theoretical yield = 10.0 g and actual yield = 7.5 g, percent yield = (7.5/10.0) × 100% = 75%.
