In the sulphur estimation,0.471 gof an organic compound gave1.44 gof barium sulfate. The percentage of sulphur in the compound is. (Nearest integer) (Atomic Mass ofBa=137u)

Answer:
42.00
Solution:

233 g of BaSO4 contains 32 g sulphur.

Amount of S in 1.44 g of BaSO4=32233×1.44

So percentage of S in 0.471 of organic compound =32233×1.440.471×100=42%
