Percent yield = (Actual yield ÷ Theoretical yield) × 100%
Theoretical yield (g) = (moles limiting reactant × molar mass of desired product)
Actual yield (g) = measured mass of the desired product obtained from the experiment
Steps:
Determine the limiting reactant
Calculate the theoretical yield (in grams) of the desired product
Measure the actual yield (in grams) of the desired product
Substitute into: percent yield = (actual ÷ theoretical) × 100%
Example calculation format:
Percent yield = (actual yield in g / theoretical yield in g) × 100%
