1.	In an estimation od sulphur by carius method, 0.2175 g of a compound gave 0.5825 g of barium sulphate. Calculate the percentage of sulphur in the compound.
Answer» Solution :MASS of the compound `=0.2175 g` Mass of barium sulphate `=0.5825 g` `{:(BaSO_(4),EQUIV,S),((137+32+64)" parts",,"32 parts"),(233 g,,32 g):}` 233g of barium sulphate contain SULPHUR `=32 g` 0.5825 g of barium sulphate contain sulphur `=32/233xx0.5825 g` PERCENTAGE of sulphur `=("Mass of sulphur")/("Mass of compound")xx100=32/233xx0.5825/0.2175xx100=36.78`.
