Answer: The percent yield of the compound is 30.86 %.
Step-by-step explanation:
To calculate the percentage yield of a compound, we use the equation:
![\%\text{ yield}=\frac{\text{Experimental yield}}{\text{Theoretical yield}}* 100](https://img.qammunity.org/2020/formulas/chemistry/high-school/t6i06lbs77uhb0at0uy3gispqvgr9ks0i3.png)
Experimental yield of compound = 25 g
Theoretical yield of compound = 81 g
Putting values in above equation, we get:
![\%\text{ yield of compound}=(25g)/(81g)* 100\\\\\% \text{yield of compound}=30.86\%](https://img.qammunity.org/2020/formulas/chemistry/college/x4axhcbu3fp9oeqebosaz5jnk9weqk2ukr.png)
Hence, the percent yield of the compound is 30.86 %.
