A conductivity cell having a cell constant of 0.5 cm–1

 filled with 0.02 M solution of KCl at 

298 K gave a resistance of 20.2 Ω. The water used for preparing the solution had a conductivity 

of 7.1 × 10–6 S cm–1. Calculate the molar conductivity of 0.02 M KCl solution

 Differentiate between conductivity and molar conductivity of a solution.
