Question

A student conducted an experiment to produce copper sulfate using a known amount of copper oxide and sulfuric acid. The expected yield was 30 grams of copper sulfate, but the student obtained only 25 grams. What is the percent yield of the reaction?

Answer 1

The percent yield of a reaction can be calculated using the following formula:Percent Yield =  Actual Yield / Theoretical Yield   100In this case, the actual yield is 25 grams, and the theoretical yield is 30 grams. Plugging these values into the formula:Percent Yield =  25 grams / 30 grams   100Percent Yield =  0.8333   100Percent Yield  83.33%The percent yield of the reaction is approximately 83.33%.
