## Calculating percentage Yield

So far, you have been calculating "theoretical yield". This means when you have solved for the limiting reagent and calculated how many grams of it would be yielded in a given situation/ equation (using limiting reagents) the number you come up with is the "theoretical yield". It's now time to take that another step further: actual yield. In a perfect world the theoretical yield would be equivalent to the actual yield. In some cases, the question will give you the actual yield and you already know how to solve for the theoretical yield. If this is the case, in order to provide the most accurate answer, you would divide the actual yield by the theoretical yield and multiply it by 100. This answer would be the "percentage yield". In other cases, you will be given the percentage yield and understand how to solve for the theoretical yield and be expected to solve for the actual yield: (Percentage Yield times theoretical yield)/ 100 equals actual yield. Below is a detailed explanation:
