Resistance of a conductivity cell filled with a solution of an electrolyte of concentration 0.1 M is 100 Ω. The conductivity of this solution is 1.29 S m–1. Resistance of the same cell when filled with 0.2 M of the same solution is 520 Ω. The molar conductivity of 0.02 M solution of the electrolyte will be
124 × 10–4 S m2 mol–1
1240 × 10–4 S m2 mol–1
1.24 × 10–4 S m2 mol–1
12.4 × 10–4 S m2 mol–1
