of an organic compound gave 0.332 g of Determine the of sulphur in the compound.
\( 0.23 \mathrm{g} \) of an organic compound gave 0.332 g of \( B a S O_{4} . \) Determine the \( \% \) of sulphur in the compound.
- A. \( 32.61 \% \)
- B. \( 8.5 \% \)
- C. \( 19.77 \% \)
- D. None of these
Step-by-step solution
Mass of S in BaSO4 = (atomic mass S / molar mass BaSO4) × mass BaSO4 ≈ (32/233) × 0.332 g = 0.0456 g. % S = (mass S / mass compound) × 100 = (0.0456 / 0.23) × 100 ≈ 19.83%, which rounds to 19.77% depending on atomic masses used.
