If a reaction has an actual yield of 5 grams and a theoretical yield of 10 grams, what is the percent yield?
Let's define those three terms before we get started:
The percent yield of a reaction is the ratio of actual yield to the theoretical yield times one-hundred percent.
The actual yield is the mass of product that was obtained in an experiment.
The theoretical yield is the mass of product calculated from the amounts of reactants used in the experiment; the amount of product that you should get in theory.
Now, to calculate the percent yield we use the equation below:
We know the actual yield and the theoretical yield, so all we have to do is divide the numbers and multiply that value by
Thus, the percent yield is
