Which law is used to find out the conductance at infinite dilution for weak electrolytes?

Raoult's law Kohlrausch's law Henry's law Faraday's law

Kohlrausch's law

According to Kohlrausch's law, "At infinite dilution, an ionic species (cation or anion) contributes a fixed value at a given temperature towards equivalent conductance of an electrolyte irrespective of other ionic species in combination with it.
