What is the conductivity of 0.02 M KCl solution if cell constant is 1.29 ~cm ⁻¹ with resistance 645 ?
Options
- A5.0 10⁻³ ⁻¹ ~cm ⁻¹
- B2.0 10⁻³ ⁻¹ ~cm ⁻¹
- C8.3 10⁻³ ⁻¹ ~cm ⁻¹
- D2.5 10⁻³ ⁻¹ ~cm ⁻¹
Correct answer
B. 2.0 10⁻³ ⁻¹ ~cm ⁻¹
Step-by-step solution
aligned & K = 1 R A ( Cell constant = A ) & K = 1 645 1.29 & =0.002 & =2 10⁻³ ⁻¹ ~cm ⁻¹ aligned
