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 mol chlorine is present in 25 g of MCl4. 1 mol chlorine will be present in 50 g of MCl4. But MCl4 contains 4 moles of chlorine then molecular weight of MCl4 = 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 mol chlorine is present in 25 g of $MC l_{4}$ . 1 mol chlorine will be present in 50 g of $MC l_{4}$ .
But $MC l_{4}$ contains 4 moles of chlorine then molecular weight of $MC l_{4}$ = 4 $\times$ 50
= 200 g $m o l^{- 1}$

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

100 g mol−1

200 g mol−1

150 g mol−1

400 g mol−1
