The equivalent conductivity refers to the normality of the solution rather than molarity. The ionic mobility is related to the molar ionic conductivity of the ion k. 145E-8 10 6 cm Ω.

Note that the molar conductivity of H ions is 5-7 times the conductivity of other small cations. It also converts resistivity to conductivity and to parts per million or milligrams per liter ppm mgL. The molar electrical conductivity Λ of an electrolyte solution is defined as the electrical conductivity divided by amount-of-substance concentration.

The lower the resistivity the more readily the material permits the flow of electric charge. In the realistic case of non-ideal solutions however the method becomes somewhat more. 7a a simple formula that relies on diffusion coefficients.
