Molar conductivity is defined as the conductivity of an electrolytic solution divided by the molar concentration of the electrolyte.

That means, it measures the efficiency of a given electrolyte that conducts electricity in solution.

It is the conducting power of all the ions produced by dissolving one mole of an electrolyte in the solution.

 Λm = k/c

Where,

Λm​ is molar conductivity.

κ is the measured conductivity (formerly known as specific conductance)

c is the electrolyte concentration.

Thus, molar conductivity and concentration of electrolyte is inversely proportional to each other.
