Yield percent = (Actual yield ÷ Theoretical yield) × 100
Actual yield = the amount of product actually obtained
Theoretical yield = the maximum amount of product expected from the balanced equation
Use the same units for actual yield and theoretical yield
Divide actual yield by theoretical yield
Multiply the result by 100 to convert to a percentage
Yield percent = 0.75 × 100 = 75% if actual yield is 75 and theoretical yield is 100
