The conductivity of 0.04 M BaCl ₂ solution is 0.0112 ⁻¹ ~cm ⁻¹ at 25^ C . what is it's molar conductivity?
Options
- A357.0 ⁻¹ ~cm ^2 ~mol ⁻¹
- B140.0 ⁻¹ ~cm ^2 ~mol ⁻¹
- C44.8 ⁻¹ ~cm ^2 ~mol ⁻¹
- D280.0 ⁻¹ ~cm ^2 ~mol ⁻¹
Correct answer
D. 280.0 ⁻¹ ~cm ^2 ~mol ⁻¹
Step-by-step solution
_ m = k 1000 M Conductivity ( k )=0.0112 ⁻¹ ~cm ⁻¹ aligned & _ m = 0.0112 1000 0.04 & =280 ⁻¹ ~cm ^2 ~mol ⁻¹ aligned
