Expert Answer:

Given:

Total mass of organic compound = 0.468 g

Mass of barium sulphate formed = 0.668 g

1 mol of BaSO4 = 233 g of BaSO4 = 32 g of sulphur

Thus, 0.668 g of BaSO4 contains of sulphur = 0.0917 g of sulphur

Therefore, percentage of sulphur = 19.59 %

Hence, the percentage of sulphur in the given compound is 19.59 %.
