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

Organic Chemistry Calculations There are three basic units for measurement in the organic laboratory – mass, volume, and number, measured in moles. Most of the other types of measurements are combinations of them, including density, molecular weight, molarity, and percent composition. Percent yield and percent

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.
