The Total solution for NCERT class 6-12
In the estimation ofsulphur by Carius method, 0.468 g of an organic sulphur compound afforded 0.668g of barium sulphate. Find out the percentage of sulphur in the given compound.
Total mass of organiccompound = 0.468 g [Given]
Mass of barium sulphateformed = 0.668 g [Given]
1 mol of BaSO4 =233 g of BaSO4 = 32 g of sulphur
Hence, the percentage ofsulphur in the given compound is 19.59 %.
