0.2 molal aqueous solution of KCl freezes at -0.680^ C . Calculate van't Hoff factor for this solution. ( K _ f =1.86 ~K ~kg ~mol ⁻¹ )

Options

  1. A1.22
  2. B1.32
  3. C1.42
  4. D1.83

Correct answer

D. 1.83

Step-by-step solution

array ll & T _ f = i m K & 0.68 ~K = i 0.2 ~mol ~kg ⁻¹ 1.86 ~K ~kg ~mol ⁻¹ & i = 0.68 0.2 1.86 =1.827 1.83 array
