Question

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

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

100gmol−1

200gmol−1

150gmol−1

400gmol−1
