The equivalent conductance of NaCl at concentration C and at infinite dilution are λc and λ∞ is given as

Debye-Huckel Onsager equation can be written as λc=λ∞−bCWhere λc=Molar conductivity of the solution at certain concentration λ∞=Limiting molar conductivityC = Concentration b = Constant that depends on temperature, charges on the ions and dielectric constant as well as viscosity of the solution
