Calculate the molality of solution if its depression in freezing point is 0.18 K . [ K _ f =1.6 ~K ~kg ~mol ⁻¹ ]

Options

  1. A0.195 m
  2. B0.156 m
  3. C0.174 m
  4. D0.113 m

Correct answer

D. 0.113 m

Step-by-step solution

aligned & T _ f = K _ f m & m = T _ f K _ f = 0.18 ~K 1.6 ~K ~kg ~mol ⁻¹ =0.113 ~m aligned
