Consider the above reaction where 6.1 g of benzoic acid is used to get 7.8 g of m-bromo benzoic acid. The percentage yield of the product is ___ .

(Round off to the Nearest integer)

[Given : Atomic masses : C=12.0 u, H:1.0 u, O:16.0 u, Br=80.0 u]

Answer:
78
Solution:

Moles of Benzoic acid =6.1122

= moles of m-bromobenzoic acid

So, weight of m-bromobenzoic acid

=6.1122×201 gm

=10.05 gm

% yield =Actual weightTheoretical weight×100

=7.810.05×100

=77.61%
