0.395g of an organic compound by Carius ...

`0.395g` of an organic compound by Carius method for the estimation of S gave `0.582g` of `BaSO_(4)`. The percentage of S in the compound is :

A

`20.24%`

B

`35.62%`

C

`12.24%`

D

`40.65%`

Text Solution

Verified by Experts

The correct Answer is:
A
`underset(233)(BaSO_(4))-=underset(32)(S)`
`233g` of `BaSO_(4)` contain sulphur `=32g`
`0.582g` of `BaSO_(4)` contain sulphur
`=(32)/(233)xx0.582`
Percentage of sulphur
`=(32xx0.582)/(233xx0.395)xx100=20.24%`
