Calculating Percent Yield in Chemical Reactions

How to calculate the percent yield in a chemical reaction?

Given the data that carbon disulfide (CS2) reacts with excess chlorine (Cl2) to produce carbon tetrachloride (CCl4) and disulfur dichloride (S2Cl2), if 73.5 g of CS2 yields 86.3 g of CCl4.

Answer:

The percent yield is 85.16%

Percent yield is the percentage ratio of the weight of the actual product obtained in a chemical reaction to the theoretical yield. To calculate the percent yield, you divide the actual yield (in this case, 86.3 g of CCl4) by the theoretical yield (calculated based on the balanced chemical equation) and then multiply the result by 100 to express it as a percentage.

In this case, the weight of CS2 given is 73.5 g and the weight of CCl4 obtained is 86.3 g. By dividing these values and multiplying by 100, we find that the percent yield is 85.16%.
