In an estimation of sulphur by Carius method, 0.234 g of an organic sulphur compound afforded 0.334 g of \( B a S O_{4} \) Find the percentage of Sulphur in the compound.

  • A. \( 12.28 \% \)
  • B. 19.60\%
  • C. \( 15.96 \% \)
  • D. 23.67\%

Step-by-step solution

Percentage of sulphur = (mass of S in BaSO₄ / mass of compound) × 100. Mass of S = (32/233) × 0.334 = 0.04585 g. Then (0.04585/0.234) × 100 = 19.60%.
