In Carius method of estimation of halogen, 0.25 g of an organic compound gave 0.15 g of silver bromide ( AgBr ). The percentage of Bromine in the organic compound is ________ ×10−1%\times 10^{-1} \% (Nearest integer).

(Given : Molar mass of Ag is 108 and Br is 80 g mol−180 \mathrm{~g} \mathrm{~mol}^{-1} )

Step-by-Step Verified Solution

% Bromine = Molar Mass of Bro mine  Molar Mass of Silver bromide × Weight of AgBr Weight of sample ×100=80188×0.1650.25×100=4800188=25.53=255×10−1
