The conductivity of 0.3 M solution of KCl at 298 ~K is 0.0627 ~S ~cm ^1 . What is its molar conductivity?
Options
- A104 ~S ~cm ^2 ~mol ⁻¹
- B188 ~S ~cm ^2 ~mol ⁻¹
- C209 ~S ~cm ^2 ~mol ⁻¹
- D109 ~S ~cm ^2 ~mol ⁻¹
Correct answer
C. 209 ~S ~cm ^2 ~mol ⁻¹
Step-by-step solution
aligned & _ m = k 1000 M & k =0.0627 ~S ~cm ^1 & M =0.3 & = 0.0627 1000 0.3 & =209 ~S ~cm ^2 ~mol ⁻¹ aligned
