Q. Consider the following reaction.
image
On estimation of bromine in $1.00 \,g$ of $R$ using Carius method, the amount of $AgBr$ formed (in $g$ ) is __
[Given : Atomic mass of $H =1, C =12, O =16, P =31, Br =80, Ag =108$ ]

Solution:

image
$\operatorname{lg~R} \rightarrow \frac{1}{250}$ moles
No. of Br Atoms $\rightarrow \frac{2}{250}$ moles
Moles of $AgBr \rightarrow \frac{2}{250}$ moles
Mass of $AgBr =\frac{2}{250} \times(108+80)=1.504$
