Answer:
Option A
Explanation:
Given,
weight of organic compound =250 mg
Weight of AgBr=141 mg
∴ According to formula of % of bromine by Carius method
% of Br= Atomic weight of Br / Molecular weight of AgBr
x Weight of AgBr/ Weight of organic bromide x 100
∴ % of Br= 80188×141250×100
= 112800047000=24 %
