In sulphur estimation, 0.157 g of an organic compound gave 0.4813 g of barium sulphate. What is the percentage of sulphur in the compound?

Text Solution

Verified by Experts

Molecular mass of `BaSO_(4) = 137+32+64 = 233 g`
`233 g BaSO_(4)` contains 32 g sulphur `0.4813 g BaSO_(4)` contains `(32xx0.4813)/(233)g` sulphur
Percentage of sulphur = `(32xx0.4813xx100)/(233xx0.157)`
`=42.10%`
