<u>Answer:</u> The percent yield of the compound is 30.86 %.
<u>Explanation:</u>
To calculate the percentage yield of a compound, we use the equation:

Experimental yield of compound = 25 g
Theoretical yield of compound = 81 g
Putting values in above equation, we get:

Hence, the percent yield of the compound is 30.86 %.
