how to find theoretical yield and percent yield. Lets suppose we have the following ratio for each yield. The theoretical yield is a term used in chemistry to describe the maximum amount of product that you expect a chemical reaction could create.

They compare the actual yield to the theoretical yield to get their percent yield. You need to begin with a balanced chemical equation and define the limiting reactant. When you measure the amount of that reactant that you will be using you can calculate the amount of product.
You determine percent yield of a chemical reaction with the following formula.
Their goal is to get a percent yield as close to 100 as they can so this is an important calculation for them. Grams of H 2 O 0436 molesx 18 GFW 7848 grams of H 2 O. What you need to do is to divide the ratios of both actual and theoretical yield and then multiply the answer with 100 to get the percentage. It indicates the percent of theoretical yield that was obtained from the final product in an experiment.
