In an estimation of bromine by Carius method, 1.6 g of an organic compound gave 1.88 g of AgBr. The mass percentage of bromine in the compound is _______.
(Atomic mass, Ag = 108, Br = 80 g mol–1)

Step-by-Step Verified Solution

Mass of organic compound = 1.6 gm

Mass of AgBr = 1.88 gm

Moles of Br = Moles of AgBr = 1.88188{{1.88} \over {188}} = 0.01

Mass of Br = 0.01 × 80 = 0.80 gm

% of Br = 0.80×1001.60{{0.80 \times 100} \over {1.60}} = 50 %
