0.16 g of an organic substance was heated in carius tube and the sulphuric acid formed was precipitated as `BaSO_(4)` with `BaCl_(2)`. The weight of the dry `BaSO_(4)` was 0.35g Find the % of sulphur

Text Solution

Verified by Experts

`% of sulphur = (32xxwt. Of BaSO_(4))/(233xx"wt. of organic substance")xx100`
`% of S= (32xx0.35)/(23xx0.16) xx100=30.04%`
