Watch the following video to get a review on the concept of percent yield and hear about the different types of questions that can be asked.

There are three variables in percent yield problems. To solve them, you need to know, or be able to calculate, two out of the three. They are as follows:

• Actual yield – the amount of product that is experimentally produced and/or recovered
• Theoretical yield – the maximum amount of product that a reaction can yield, usually found by stoichiometry
• Percent yield – the ratio of actual yield to theoretical yield in percent form
