0.2595 g of organic compound when treated by carius method gave 0.35 g of `BaSO_(4)`. Calculate the percentage of sulphur in the compound.

Text Solution

Verified by Experts

The correct Answer is:
`18.52`

Percentage of sulphur `=32/233xx ("Mass of "BaSO_(4))/("Mass of compound")xx100=32/233xx0.35/0.2595xx100=18.52%`
