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]

Step-by-Step Verified 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'.
