An organic compound contains C,HC, H and SS. The minimum molecular weight of the compound containing 88% Sulphur is

Options

  1. A600gmol−1600gmo{l}^{- 1}
  2. B200gmol−1200gmo{l}^{- 1}
  3. C400gmol−1400gmo{l}^{- 1}
  4. D300gmol−1300gmo{l}^{- 1}

Correct answer

C. 400gmol−1400gmo{l}^{- 1}

Step-by-step solution

% of Sulphur =weightofsulphurweightofcompound×100=8= \dfrac{weightofsulphur}{weightofcompound} \times 100 = 8

∴32weightofcompound=8100∴ \dfrac{32}{weightofcompound} = \dfrac{8}{100}

∴weightofcompound=400gmol−1∴ weightofcompound = 400gmo{l}^{- 1}
