Step-by-step explanation:
To calculate the percent yield, we need to compare the actual yield to the theoretical yield. The theoretical yield is the amount of product that would be obtained if the reaction went to completion based on the stoichiometry of the balanced equation.
Given:
Theoretical yield = 21 g
Actual yield = 11 g
We can calculate the percent yield using the formula:
Percent Yield = (Actual Yield / Theoretical Yield) * 100
Percent Yield = (11 g / 21 g) * 100
Percent Yield = 52.38%
Therefore, the percent yield for the chemical reaction is 52.38%.
