Question

An organic compound contains C, H and S. The minimum molecular weight of the compound containing 8% sulphur is: (atomic weight of S=32 amu) (A) 200 g mol-1 (B) 400 g mol-1 (C) 600 g mol-1 (D) 300 g mol-1

Tardigrade Admin · Accepted Answer

%of sulphur=(wt of sulphur/wt of compound)×100=8 ∴ (32/wt. of compound)=(8/100) ∴ wt. of compound =400 g mol-1

Q. An organic compound contains C, H and S. The minimum molecular weight of the compound containing 8% sulphur is :
(atomic weight of S=32 amu)

$200 g mol X^{- 1}$

$400 g mol X^{- 1}$

$600 g mol X^{- 1}$

$300 g mol X^{- 1}$

$% o f s u lp h u r = \frac{wt o f s u lp h u r}{wt o f co m p o u n d} \times 100 = 8$
$∴ \frac{32}{wt . o f co m p o u n d} = \frac{8}{100} ∴ wt . o f co m p o u n d = 400 g m o l^{- 1}$
