Percent yield compares the actual amount of product obtained in a reaction to the theoretical maximum (calculated from stoichiometry). It reflects efficiency and accounts for side reactions, incomplete reactions, and purification losses.
Guide étape par étape
- 1Calculate theoretical yield from stoichiometry using limiting reagent
- 2Weigh or measure actual product obtained
- 3Percent yield = (Actual yield / Theoretical yield) × 100%
