What is the cell constant of a cell of KCI containing `N//50` solution, if the conductivity and resistance of cell is `0.002765 S cm^(-1)` and 400 ohm respectively.

A

`6.91 cm^(-1)`

B

`1.106 cm^(-1)`

C

`14.46 cm^(-1)`

D

`2.212 cm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B

We know conductivity= conductance `xx` cell constant
Conductivity = Conductance `xx` Cell constant = `(1)/(R) xx "Cell constant"`
Cell constant = Conductivity `xx` R
`= 0.002765 xx 400= 1.106 cm^(-1)`
