# How to Calculate and Solve for Specific Surface Area due to Coverage | Mineral Processing

Last Updated on December 10, 2021

The image above represents specific surface area due to coverage.

To compute for specific surface area due to coverage, three essential parameters are needed and these parameters are Assumed Total Volume Coverage of Gas (Vm), Surface Energy / Average Area of One Adsorbate Molecule in Complete Monolayer (σ) and Avogadro’s Constant (NA).

The formula for calculating specific surface area due to coverage:

A = VmσNA/22414

Where:

A = Specific Surface Area due to Coverage
Vm = Assumed Total Volume Coverage of Gas
σ = Surface Energy / Average Area of One Adsorbate Molecule in Complete Monolayer

Let’s solve an example;
Find the specific surface area due to coverage when the assumed total volume coverage of gas is 4, the surface energy / average area of one adsorbate molecule in complete monolayer is 6 and the avogadro’s constant is 6.023E23.

This implies that;

Vm = Assumed Total Volume Coverage of Gas = 4
σ = Surface Energy / Average Area of One Adsorbate Molecule in Complete Monolayer = 6
NA = Avogadro’s Constant = 6.023E23

A = VmσNA/22414
A = (4)(6)(6.023e+23)/22414
A = 1.4455199e+25/22414
A = 644918354599803600000

Therefore, the specific surface area due to coverage is 644918354599803600000 m²/g.
