This video shows you how to calculate the theoretical and percent yield in chemistry. Calculate the percentage yield. The formula for calculating the percent yield is.
To compare the amount of product obtained from a reaction with the amount that should have been obtained they use percent yield.
The percent yield is the ratio of the actual yield to the theoretical yield expressed as a percentage. So to stop you from wondering how to find theoretical yield here is the theoretical yield formula. Percentage yield of NaCl 850 grams 993 grams 100. You determine percent yield of a chemical reaction with the following formula.
