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

Correct answer
40
Step-by-step explanation
nAgBr = = 103 mol
nBr = nAgBr = 0.001 mol
massBr = (0.001 80) gm = 0.08 gm
mass% =
nBr = nAgBr = 0.001 mol
massBr = (0.001 80) gm = 0.08 gm
mass% =
