WitrynaThe theoretical yield of 100 g is the calculated amount of product, assuming that the reaction is 100% efficient. The percentage yield is the ratio of actual yield to theoretical yield expressed as a percentage: (37 g/100 g) × 100% = 37%. 3. Formula for percentage yield. percentage yield = actual yield ÷ theoretical yield × 100%.
