The specific conductance of a 0.1 N KCl ...

The specific conductance of a `0.1 N KCl` solution at `23^(@)C` is `0.012 ohm^(-1) cm^(-1)`. The resistance of cell containing the solution at the same tempreature was found to be `55 ohm`. The cell constant will be

A

`0.0616 cm^(-1)`

B

`0.66 cm^(-1)`

C

`6.60 cm^(-1)`

D

`660 cm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
Specific conductance of the solution (k) = `0.012 ohm^(-1) cm^(-1)` and resistance (R) = 55 ohm
Cell constant = Specific conductance `xx` Observed resistance = `0.012 xx 55 = 0.66 cm^(-1)`
