What is the Percent yield made if 3.9 grams of a substance were made experimentally while you calculated 3.6 grams of substance using Stoichiometry?

108.3%

Explanation:

Percent yield is the concept where you calculate the ratio or percent of actual yield to theoretical yield.

Actual yield is what you actually experimentally got.

Theoretical yield is what you expected to get from math.

Always remember the two terms above will never be same in real life because we do not have perfect system where we can account for energy loss and such in daily life.

Percent yield= actual yield/theoretical yield  x 100%

                    =  3.9/3.6 x 100%

                     = 108.3%

Percent yields are understandably less than 100% because of the reasons indicated earlier like imperfect systems. However, percent yields greater than 100% are possible, such as our question, if the measured product of the reaction contains impurities that cause its mass to be greater than it actually would be if the product was pure.
