In the estimation of sulphur by Carius m...

In the estimation of sulphur by Carius method, `0.480g` of an organic compound gives `0.699g` of barium sulphate. The percentage of sulphur in this compound is
[Atomic masses : `Ba=137`, `S=32`, `O=16`]

A

`20%`

B

`15%`

C

`35%`

D

`30%`

Text Solution

Verified by Experts

The correct Answer is:
A
Percentage of `S=(32)/(233)xx("Mass of"BaSO_(4)"formed")/("Mass of compound taken")xx100`
`=(32)/(233)xx(0.699)/(0.480)xx100=20%`
