how to calculate percentage yield of product. Amount of product observed at the conclusion of the experiment. Be sure that actual and theoretical yields are both in the same units so that units cancel in the calculation.
Start with a balanced chemical equation. 37 g100 g 100 37 3. How to calculate the percent yield of a chemical reaction.
To compare the amount of product obtained from a reaction with the amount that should have been obtained they use percent yield.
1291 Percent Yield Actual Yield Theoretical Yield 100. The actual yield is the amount of product that is actually formed when the reaction is carried out in the laboratory. The percent yield is simply the actual yield divided by theoretical yield multiplied by 100. The formula looks like this.
