kappa= GG * where kappa= specific conductance =0.0112 ohm -1 cm -1 G = conductance =(1/55)=0.01818 ohm -1 G *= cell constant 0.0112=0.01818 × G * G *=0.616 cm -1

Q. Specific conductance of $0.1 N K Cl$ solution at $2 3^{\circ} C$ is $0.012 o h m^{- 1} c m^{- 1}$ . Resistance of cell containing the solution at same temperature was found to be $55 o hm$ . The cell constant is:

$0.0616 c m^{- 1}$

$0.616 c m^{- 1}$

$6.16 c m^{- 1}$

$616 c m^{- 1}$

$κ = G G^{}$
where $κ =$ specific
conductance $= 0.0112 o h m^{- 1} c m^{- 1}$
$G =$ conductance $= \frac{1}{55} = 0.01818 o h m^{- 1}$
$G^{} =$ cell constant
$0.0112 = 0.01818 \times G^{}$
$G^{} = 0.616 c m^{- 1}$
