`0.15` gm of an organic compound gave `0.12` gm of silver bromide by the Carius method. Find the percentage of bromine in the compound.

Text Solution

Verified by Experts

Mass of `AgBr` formed `= 0.12` g
`underset(188)(AgBr) -= underset(80)(Br)`
`0.12` g of `AgBr` will contain bromine `= (80 xx 0.12)/( 188) = 0.051` g
`therefore` Percentage of bromine `= (0.051)/( 0.15) xx 100`
`= 34.04%`
