When 0.15 g of an organic compound was analyzed using Carius method for estimation of bromine, 0.2397 g of AgBr was obtained. The percentage of bromine in the organic compound is _________.(Nearest integer)

[Atomic mass : Silver =108, Bromine =80]

Solution

Moles of Br= Moles of AgBr obtained

⇒ Mass of Br=0.2397188×80 g 

therefore %Br in the organic compound

=WBrWT×100

=0.2397×80188×0.15×100=0.85×80

=68

⇒ Nearest integer is '68'
