Conductivity cell is filled with 0.01 M KCl gives a resistance of 484 and conductivity of 0.00141 ⁻¹ ~cm ⁻¹ at 25^ C . What is cell constant?
Options
- A0 682 ~cm ⁻¹
- B0 341 ~cm ⁻¹
- C0.751 ~cm ⁻¹
- D0 510 ~cm ⁻¹
Correct answer
A. 0 682 ~cm ⁻¹
Step-by-step solution
aligned C=0.01 M , R &=484 , k =0.00141 ⁻¹ ~cm ⁻¹, b=? Cell constant, b &=k R &=0.00141 ⁻¹ ~cm ⁻¹ 484 b &=0.682 ~cm ⁻¹ aligned
