Molal depression constant for a liquid is 2.77^ C kg mol ⁻¹ , in Kelvin scale it's value is
Options
- A275.77 ~K ~kg ~mol ⁻¹
- B271.77 ~K ~kg ~mol ⁻¹
- C2.77 ~K ~kg ~mol ⁻¹
- D27.7 ~K ~kg ~mol ⁻¹
Correct answer
C. 2.77 ~K ~kg ~mol ⁻¹
Step-by-step solution
K _ f = T _ f m unit of K _ f ^ C kg mol ⁻¹ Or K kg. mol ⁻¹ Temperature difference will be same in ^ C and K . K _ f =2.77 ~K ~kg mol ⁻¹
