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 ]

Correct answer

0

Step-by-step solution

Moles of Benzoic acid = 6 . 1 122 = moles of m-bromobenzoic acid So, weight of m-bromobenzoic acid = 6 . 1 122 × 201   gm = 10 . 05   gm % yield = Actual   weight Theoretical   weight × 100 = 7 . 8 10 . 05 × 100 = 77 . 61 %
