Q. The resistance of the cell containing $K Cl$ solution at $2 3^{\circ} C$ was found to be $55 Ω$ . Its cell constant is $0.616 c m^{- 1}$ . The conductivity of $K Cl$ solution $(Ω^{- 1} c m^{- 1})$ is

$1.21 \times 1 0^{- 3}$

$1.12 \times 1 0^{- 2}$

$1.12 \times 1 0^{- 3}$

$1.21 \times 1 0^{- 2}$

Conductivity, $κ = \frac{Cell constant}{Resistance} = \frac{0.616}{55}$
$= 1.12 \times 1 0^{- 2} Ω^{- 1} c m^{- 1}$
