Of course, you can also use our theoretical yield calculator to find the calculated yield of a reaction. But this calculator enables you to calculate yield values. Theoretical yield = actual yield / percentage yield × 100% No need to do manual calculations with yield formulas when you have this calculator. It gives you the easiest way to find the value of yield of a theoretical equation. The user friendly tool saves a lot of time and. The calculator above uses this equation to solve the actual yield given these inputs. Percent yield calculator is a very useful tool for students of chemistry. Use the online Percent Yield Calculator to determine the Percent Yield of a Chemical Reaction instantly. Actual Yield FormulaĪctual yield = percent yield / 100% × theoretical yield You can also calculate the actual and theoretical yield by modifying the percent yield formula above to derive the following formulas. Calculating Percent Yield Example Now that we know the steps to calculate percent yield, let’s walk through an example: Use the balanced chemical reaction below. Multiplying that by 100 gives you the percent yield. How to Find the Actual & Theoretical Yield Dividing the actual by the theoretical gives you the fraction of product you made. Over 90% yield is considered excellent, 80-90% is deemed very good, 70-80% is good, 50-70% is fair, and below 40% is poor. You might be wondering what a good percent yield value might be. The goal of a chemist working on improving a reaction will be to improve the yield. Since it’s a direct measure of the efficiency of a reaction, it is an important indicator of the amount of reactant required to make an actual product. Percent yield is a very important consideration in commercial and industrial chemistry. So we might simplify the concept of percent error to be 100% minus the percent yield, or basically the remaining reactant that was not reacted in the experiment. So, in the example above, the percent error is 7.8%.Ī keen observer might have noticed that the percent yield of 92.2% added with the percent error of 7.8% equals exactly 100%. Or the units of both actual yield and theoretical yield must be the same. Percentage yield (15 ÷ 20) × 100 75 Losing product A 100 per cent yield means that no product has been lost, while a 0 per cent yield means that no product has been made. The unit of all reactants must be the same. Here, the above value of percent yield indicates that the above chemical reaction gives 83 product or 83 reactants are converted to product. Of course, you can also use our theoretical yield calculator to find the calculated yield of a reaction.For example, let’s calculate the percent error of the reaction above with a theoretical yield of 4.85 g and an actual yield of 4.47 g. Percent yield () (9.6 g / 11.56g) X 100Percent yield () 83. The calculator above uses this equation to solve the actual yield given these inputs. You can also calculate the actual and theoretical yield by modifying the percent yield formula above to derive the following formulas. To calculate percent yield, you simply take actual yield 1.099 grams of sodium bromide, divided by the theoretical yield 1.452 grams of sodium bromide. How to Find the Actual & Theoretical Yield Water can be produced by reaction of hydrogen and oxygen gas according to this equation. Over 90% yield is considered excellent, 80-90% is deemed very good, 70-80% is good, 50-70% is fair, and below 40% is poor. Find the atom economy and percentage yield of chemical reactions. The goal of a chemist working on improving a reaction will be to improve the yield. The percentage yield is the actual amount of product produced, divided by the theoretical maximum amount of product. ![]() For example, let’s calculate the percent error of the reaction above with a theoretical yield of 4.85 g and an actual yield of 4.47 g. ![]()
