📊 Percent Yield Calculator
Calculate the percent yield of a chemical reaction using (actual yield / theoretical yield) × 100.
What is Percent Yield?
Percent yield measures the efficiency of a chemical reaction. The formula is: Percent Yield = (Actual Yield / Theoretical Yield) × 100%. The theoretical yield is the maximum amount of product predicted by stoichiometry, while the actual yield is the amount actually obtained from the experiment.
Why Percent Yield Matters
Percent yield is rarely 100% due to side reactions, incomplete reactions, loss during transfer, and purification steps. In industrial chemistry, maximizing percent yield is critical for cost efficiency. A percent yield over 100% may indicate impurities or measurement errors.
