In Carius method for estimation of halogens, 0.2g0 . 2g of an organic compound gave 0.188g0 . 188g of AgBr.AgBr . The percentage of bromine in the compound is __________. (Nearest integer)

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

Correct answer

0

Step-by-step solution

=Atomic mass ofXMolecular mass ofAgX×wt. ofAgXwt. of organic helides= \dfrac{\text{Atomic mass of}X}{\text{Molecular mass of}AgX} \times \dfrac{\text{wt. of}AgX}{\text{wt. of organic helides}}

=80188×0.1880.2×100=40= \dfrac{80}{188} \times \dfrac{0 . 188}{0 . 2} \times 100 = 40 %
