Kohlrausch’s Law Formula
At infinite dilution each ion migrate independently of its co-ion and make its own contribution to the total molar conductivity of irrespective nature of other ion.

Or
Limiting molar conductance of for any electrolyte is the summation of individual contribution of cation and anion of that electrolyte.
Formula:
λ°=λ° + λ°–
λ°^+ = molar conductivity of cation ay infinite dilution
λ°– = molar conductivity of anion ay infinite dilutionλ° = λ° + λ°–
Infinite dilution:
Infinite dilution means zero concentration of solution or (zero concentration of molar conductance of solution).
