हिन्दीIn the estimation of sulphur by Carius method, 0.32 g of an organic compound gave 0.466 g of barium sulphate. What is the percentage of sulphur in the compound? (Molar mass of \( \text{BaSO}_4 = 233\text{ g mol}^{-1} \), Atomic mass of \( \text{S} = 32\text{ u} \))
View Answer & Solution
Correct answer · Option A
20.0%
Explanation
\( \%\text{S} = \frac{32 \times 0.466 \times 100}{233 \times 0.32} = \frac{14.912}{0.7456} = 20.0\% \).
