The image of mobility of an ionic specie is shown below.

To compute for mobility of an ionic specie, five essential parameters are needed and these parameters are **Valence (n _{I}), Electrical Charge (e), Diffusion Coefficient (D_{I}), Boltzmann’s Constant (K)** and

**Temperature (T).**

The formula for calculating the mobility of an ionic specie:

μ_{I} = ^{nIeDI}/_{KT}

Where:

μ_{I} = Mobility of an Ionic Specie

n_{I} = Valence

e = Electrical Charge

D_{I} = Diffusion Coefficient

K = Boltzmann’s Constant

T = Temperature

Let’s solve an example;

Find the mobility of an ionic specie when the valence is 18, the electrical charge is 9, the diffusion coefficient is 12, the boltzmann’s constant is 6 and the temperature is 3.

This implies that;

n_{I} = Valence = 18

e = Electrical Charge = 9

D_{I} = Diffusion Coefficient = 12

K = Boltzmann’s Constant = 6

T = Temperature = 3

μ_{I} = ^{nIeDI}/_{KT}

μ_{I} = ^{(18)(9)(12)}/_{(6)(3)}

μ_{I} = ^{1944}/_{18}

μ_{I} = 108

Therefore, the **mobility of an ionic specie **is **108 m²/(V. s).**
