JEE Main 2006 Chemistry question
Resistance of a conductivity cell filled with a solution of an electrolyte of concentration 0.1M is 100Ω. The conductivity of this solution is 1.29 S . Resistance of the same cell when filled with 0.2M of the same solution is 520Ω. The molar conductivity of 0.02M solution of the electrolyte will be
Answer: (4)
Solution
Cell constant m⁻¹. For the second solution, S m⁻¹. Taking its concentration as printed (0.2 M = 200 mol m⁻³):
