1.	0.16 g of an organic compound was heated in a carius tube and H_(2)SO_(4) acid formed was precipitated with BaCl_(2). The mass of BaSO_(4) was 0.35 g. Find the percentage of sulphur.
Answer» Solution :Weight of organic SUBSTANCE (w) = 0.16 G Weight of BARIUM SULPHATE (x) = 0.35 g `"Percentage of Sulphur"=(32)/(233) xx (x)/(w) xx 100=(32)/(233) xx (0.35)/(0.16) xx 100=30.04%`
