What will be the concentration of NaCl solution, if the molar conductivity and conductivity of NaCl solution is 124 3 ⁻¹ ~cm ² ~mol ⁻¹ and 1 243 10⁻⁴ ⁻¹ ~cm ² respectively?
Options
- A0.001 mol L ⁻¹
- B0.01 ~mol ~L ⁻¹
- C0.02 mol I₁⁻¹
- D0.1 ~mol ~L ⁻¹
Correct answer
A. 0.001 mol L ⁻¹
Step-by-step solution
(D) array l =124.3 ⁻¹ ~cm ² ~mol ⁻¹, k =1.243 10⁻⁴ ⁻¹ ~cm ² C =? = 1000 k C C = 1000 k C = 1000 1.243 10⁻⁴ 124.3 =0.001 ~mol ~L ⁻¹ array
