The percentage yield obtained when 0.303 g of 4-aminobenzoic acid react with excess ethanol is 87.1%
- We'll begin by calculating the theoretical yield of benzocaine. This can be obtained as follow:
From the balanced equation given in the question above,
137.14 g of 4-aminobenzoic acid reacted to produce 165.19 g of benzocaine.
Therefore,
0.303 g of 4-aminobenzoic acid will react to produce =[tex]\frac{0.303 * 165.19}{137.14}[/tex] = 0.365 g of benzocaine.
Thus, the theoretical yield of benzocaine is 0.365 g
- Finally, we shall determine the percentage yield. This can be obtained as follow:
Actual yield of benzocaine = 0.318 g
Theoretical yield of benzocaine = 0.365 g
Percentage yield =?
[tex]Percentage yield = \frac{Actual}{Theoretical} * 100\\\\= \frac{0.318}{0.365} * 100\\\\[/tex]
= 87.1%
Therefore, the percentage yield for the reaction is 87.1%
