How to Evaluate Kohlrausch Law?

Kohlrausch Law evaluator uses Molar Conductivity = Limiting Molar Conductivity-(Kohlrausch Coefficient*sqrt(Concentration of Electrolyte)) to evaluate the Molar Conductivity, The Kohlrausch Law states that the migration of an ion at infinite dilution is dependent on the nature of the solvent and on the potential gradient but not on the other ions present. Molar Conductivity is denoted by Λ_m symbol.

How to evaluate Kohlrausch Law using this online evaluator? To use this online evaluator for Kohlrausch Law, enter Limiting Molar Conductivity (Λ0m), Kohlrausch Coefficient (K) & Concentration of Electrolyte (c) and hit the calculate button.
