25 g of MCl₄ contains 0.5 mole chlorine then its molecular weight is (Punjab PMET 2007)

A.100 g mol–1

B.200 g mol–1✓ Correct

C.150 g mol–1

D.400 g mol–1

Explanation

Given, 25 g 4 MCl contains 0.5 moles of chlorine 1 mole of 4 MCl contains 4 moles of chlorine atoms Moles of chlorine atoms Mass of 4 MCl 0.5 25 g 4 X Solving for x, we get 1 25 4 100 200 0.5 0.5 x x gmol Therefore, the molecular weight of 4 MCl is 200 1 gmol
