Tap to reveal answer
To find the percent conversion, use the following equation:
Initially there are 3 mols of 
. We know that every 1 mol of 
that is consumed in the reaction yields 1 mol of 
. Therefore, the final amount of 
in mols is
Plugging this into the above equation gives a conversion rate of 58%.
To find the percent conversion, use the following equation:

Suppose that a chemist working in a lab is trying to synthesize caffeine. In doing so, he predicts that he can produce 
of caffeine. After the chemist finishes synthesizing the caffeine, he weighs it only to find out that 
are produced. What is the percent yield of caffeine in this synthesis process?

When chemists synthesize compounds in the lab, a theoretical yield can be calculated by using knowledge of the full, balanced chemical equation, as well as the starting amounts of all reagents including the limiting reagent. However, due to a variety of factors, the actual yield obtained at the end of the experiment is nearly always going to be lower than the theoretical yield. Some of the things that can cause this are experimental error and side reactions, among others. Thus, chemists usually take the ratio of actual yield to theoretical yield to give the percent yield.
This means that the overall process was 
efficient.
