Resistance of a conductivity cell filled...

Resistance of a conductivity cell filled with 0.1 M KC1 solution is 100 ohm. If the resistance of the same cell when filled with 0.02 M KC1 solution is520 ohms, calculate the conductivity and molar conductivity of 0.02 M KC1 solution. The conductivity of `0.1molL^(−1)` KCl solution is `1.29×10 ^(−2) Ω ^(−1) cm ^(−1)` .
