25 g of MCl4 contains 0.5 mole chlorine then its molecular weight is

Question

25 g of MCl4 contains 0.5 mole chlorine then its molecular weight is (A) 100 g mol -1 (B) 200 g mol -1 (C) 150 g mol -1 (D) 400 g mol -1

Tardigrade Admin · Accepted Answer

0.5 mole chlorine is present in 25 g of M C l4 1 mole chlorine will be present in 50 g of 50 g But 50 g contain 4 moles of chlorine then, molecular weight of M C l4=4 × 50 =200 g mol -1

Q. $25 g$ of $MC l_{4}$ contains $0.5$ mole chlorine then its molecular weight is

$100 g m o l^{- 1}$

$200 g m o l^{- 1}$

$150 g m o l^{- 1}$

$400 g m o l^{- 1}$

$0.5$ mole chlorine is present in $25 g$ of $MC l_{4}$
$1$ mole chlorine will be present in $50 g$ of $50 g$
But $50 g$ contain $4$ moles of chlorine then, molecular weight of
$MC l_{4} = 4 \times 50$
$= 200 g m o l^{- 1}$
