Question

0.36g of an organic compound containing sulphur produced H2SO4 by Carius method, which on treatment with BaCl2 produced quantitatively 0.2330g of BaSO4. Calculate the percentage of S in the compound..??

Answer 1

Answer:

8.89%

Explanation:

Moles of S in BaSO4 = 1 * Mole of BaSO4

                                   = 0.2330/233 = 0.001

Weight of S = 0.001 * 32 g = 0.032g

Percentage of S = 0.032/0.36 * 100 = 8.89%.
