Derive a relation between ionic mobility and molar ionic conductance

The ionic mobility (μ) is defined as the velocity attained by an ion moving through a gas under unit electric field.
Ionic mobility or Ionic conductance is the conductivity of a solution containing 1 g ion, at infinite dilution, when two sufficiently large electrodes are placed 1 cm apart.
Ionic mobilities ( λa or λc) ∝ speeds of ions (ua or uc)

Unit of ionic mobility is Ohm–1 cm2 or V–1S-1cm2

Ionic mobility and transport number are related as, 

λa or λc = ta or tc × λ ∞

Absolute ionic mobilityis the mobility with which the ion moves under unit potential gradient. It's unit is cm sec–1.

Absolute ionic mobility = Ionic mobility/96,500
