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 beA. `0.142 cm^(-1)`B. `0.66 cm^(-1)`C. `0.918 cm^(-1)`D. `1.12 cm^(-1)`

Answer» Correct Answer - B
The specific conductance (or conductivity) of the solution is given by the equation :
`kappa = (1)/(c) xx` cell constant
Thus, the cell constant `(G^(**))` is given by the equation:
`(G^(**)) = R kappa`
`= (55 "ohm")(0.012 "ohm"^(-1)cm^(-1))`
`= 0.66 cm^(-1)`
