The resistance of a conductivity cell of 0.1 M KCl solution is 120 ohm and conductivity is 1.64 10⁻⁴ ~S ~cm ⁻¹ . What is the value of cell constant?
Options
- A0.0136 ~cm ⁻¹
- B0.0618 ~cm ⁻¹
- C0.0196 ~cm ⁻¹
- D0.0731 ~cm ⁻¹
Correct answer
C. 0.0196 ~cm ⁻¹
Step-by-step solution
aligned & Conductivity ( k )= Cell constant R & Cell constant = k R & =1.64 10⁻⁴ ~S ~cm ⁻¹ 120 & =0.0196 ~cm ⁻¹ aligned
