In Carius method for estimation of halogens, $0.2 g$ of an organic compound gave $0.188 g$ of $AgBr .$ The percentage of bromine in the compound is __________. (Nearest integer)

[Atomic mass: $Ag = 108, Br = 80$ ]

Answer:

Solution:

$= \frac{Atomic mass of X}{Molecular mass of AgX} \times \frac{wt. of AgX}{wt. of organic helides}$

$= \frac{80}{188} \times \frac{0.188}{0.2} \times 100 = 40 %$
