0.4g of an organic compound gave 0.188g of silver bromide by a halogen estimation method. The percentage of bromine in the compound is : (at.mass of Ag=108, Br=80) :

Answer»

`39.8%`
`46.0%`
`20.0%`
`40.0%`

Solution :MASS of HALOGEN in `0.4g` of COMPOUND
`=(80)/(188)xx0.188=0.80g`
`%Br=(0.08)/(0.4)xx100=20%`
