What is the molar conductivity of 0.05 M solution of sodium hydroxide, if its conductivity is 0.0118 ~S ~cm ⁻¹ at 298 ~K ?
Options
- A236 ~S ~cm ^2 ~mol ⁻¹
- B423 ~S ~cm ^2 ~mol ⁻¹
- C354 ~S ~cm ^2 ~mol ⁻¹
- D590 ~S ~cm ^2 ~mol ⁻¹
Correct answer
A. 236 ~S ~cm ^2 ~mol ⁻¹
Step-by-step solution
aligned & M =0.05, k ( conductivity )=0.0118 Scm ⁻¹ & _ m = k 1000 M & _ m = 0.0118 1000 0.05 & _ m =236 Scm ^2 mol ⁻¹ aligned
