A student has been given 0.314 g of an organic compound and asked to estimate Sulphur. During the experiment, the student has obtained 0.4813 g of barium sulphate. The percentage of sulphur present in the compound is _ _ _ _ . (Given Molar mass in g mol ⁻¹ ~S : 32, BaSO ₄: 233 )

Options

  1. A48.24 %
  2. B63.15 %
  3. C21.05 %
  4. D42.10 %

Correct answer

C. 21.05 %

Step-by-step solution

Given: Mass of organic compound = 0.314 g, Mass of BaSO ₄ obtained = 0.4813 g. %S = 32 233 0.4813 0.314 100 = 32 0.4813 100 233 0.314 = 1540.16 73.162 = 21.05 %
