To get percent yield, insert the values in the percent yield formula, So the percent yield equation will be Suppose you have been asked to calculate the percent yield of a reaction whose theoretical yield is 95g while the actual yield is 92.2g. Step 4: Add the Values in the Percent Yield Formula At the same time, the amount of CO left even after the completion of the reaction. Suppose you have been asked to find the theoretical yield of methyl hydroxide produced by 1.2 tons of hydrogen gas. Thus, the theoretical yield of water produced by the reaction of two moles of hydrogen and one mole of oxygen will be 36g. The one used to find theoretical yield at the industrial level and the other that is used to calculate theoretical yield at more minor levels (for few moles).įor this purpose, all you have to do is to multiply the number of moles with the molar mass of each reactant and then sum up all the values together, such as There are two main methods to find the theoretical yield of a reaction. The third step in finding the percentage yield is to calculate the theoretical yield of chemical reaction. You can also balance your equations using online chemical equation balancer on the home page of this website. You have to weigh your product using a balance and note the value of the total product mass. If you are performing the chemical reaction by yourself, then there will be no problem in calculating the actual yield.

If the percent yield of a reaction is 60%, then it means that you got the actual yield equal to 60% of your theoretical yield. To get the value of percentage yield, you need to find out the values for theoretical and actual yield first and just putting in in the percent yield formula. The percent yield formula makes it easy for us to learn how to find percent yield. Percent yield = Theoretical yield ÷ Actual yield × 100 Going further, we will use the percent yield formula for calculating the percent yield equation. ![]() The percent yield definition tells the ratio of both these types of yield, which helps us to calculate percent yield of chemical reactions. The reason is the failure of some reactants to change into products due to various factors like unforeseen problems, the presence of contaminants, and mass-energy conversion. As stated before, the theoretical yield is always higher than that of the actual yield. In order to calculate percent yield equation, first we need to understand the requirements. These steps are: Step 1: Understand the requirements You can find the percent yield of chemical reactions using 4 simple steps. How to Calculate Percent Yield of a Reaction Step by Step?
