Verified Answer :

The formula actual yield /
theoretical yield is used to calculate the percent yield of a reaction.
This value is a measure of how much product is produced relative to the what is
supposed to be produced.

Percent yield = 22.0 / 26.0 x 100 =  84.6%

Hope this answers the question. Have a nice day.

Answer:

84.6 %

Explanation:

Percent yield = actual yield/ theoretical yield x 100

Percent yield is the ratio of the actual yield to the theoretical yield  

Given,  

Actual yield = 22 g

Theoretical yield = 26 g  

Percent yield = \(\frac{22 g x 100}{26 g}\) = 84.6%
