Percent yield = 2.43 g 2.96 g •100 / 0.894 = 92% Calculate Percent Yield: Since not all of the crude product was recrystallized, we need to account for that in the calculation of percent yield. In other words, the percent yield should reflect what you would have gotten if you purified the whole batch.

Calculating Percent Yield Organic reactions typically do not give 100% yields, meaning all of the starting material does not get converted to the product. The percent of starting material that is converted to product in a chemical reaction is referred to as the percent yield. The percent yield can be calculated if the following information is ...

To determine the percent yield: Divide the actual yield made in the lab by the calculated theoretical amount, and multiply by 100. For a synthesis – to find the overall percent yield, multiply the individual percent yields of every step by each other (ex. 3 steps, all 30% yield – 0.30 x 0.30 x 0.30 = 0.27
