The equivalent mass of a certain bivalent metal is 20 . The molecular mass of its anhydrous chloride is

Options

  1. A111
  2. B55.5
  3. C75.5
  4. D91

Correct answer

A. 111

Step-by-step solution

Atomic weight of metal = equivalent weight x valency =20 2=40 Molecular formula of metal chloride = MCl ₂ Molecular mass of MCl ₂=40+2 35.5=111 ~g ~mol ⁻¹
