The image above represents the mass of an element.

To compute for the mass of an element, two essential parameters are needed and these parameters are **Electrochemical Equivalence of the Substance (Z)** and **quantity of charge (Q).**

The formula for calculating mass of an element:

M = ZQ

Where;

M = Mass of the element

Z = Electrochemical Equivalence of the Substance

Q = Quantity of Charge

Let’s solve an example;

Find the mass of an element when the Quantity of charge is 28 and Electrochemical Equivalence of the Substance is 32.

This implies that;

Z = Electrochemical Equivalence of the Substance = 32

Q = Quantity of Charge = 28

M = ZQ

M = 32 x 28

M = 896

Therefore, the **mass of an element** is **896 kg.**

**Calculating the Electrochemical Equivalence of the Substance when the Mass of an Element and Quantity of Charge is Given.**

Z = ^{M} / _{Q}

Where;

Z = Electrochemical Equivalence of the Substance

M = Mass of the element

Q = Quantity of Charge

Let’s solve an example;

Find the Electrochemical Equivalence of the Substance when the Quantity of charge is 12 and mass of an element is 120.

This implies that;

M = Mass of the element = 120

Q = Quantity of Charge = 12

Z = ^{M} / _{Q}

Z = ^{120} / _{12}

Z = 10

Therefore, the **Electrochemical Equivalence of the Substance **is **10.**

**Calculating the Quantity of Charge when the Mass of an Element and Electrochemical Equivalence of the Substance is Given.**

Q = ^{M} / _{Z}

Where;

Q = Quantity of Charge

M = Mass of the element

Z = Electrochemical Equivalence of the Substance

Let’s solve an example;

Find the Quantity of charge when the Electrochemical Equivalence of the Substance is 20 and mass of an element is 240.

This implies that;

M = Mass of the element = 240

Z = Electrochemical Equivalence of the Substance = 20

Q = ^{M} / _{Z}

Q = ^{240} / _{20}

Q = 12

Therefore, the **quantity of charge** is **12 Coulomb (C).**
