Variables Used
Mass of Adsorbent - (Measured in Kilogram) - The Mass of Adsorbent is the weight of the solid material on which gas is adsorbed.
Mass of Gas Adsorbed - (Measured in Kilogram) - The Mass of Gas Adsorbed is the amount of gas reacted with the adsorbent.
Adsorption Constant - The Adsorption Constant depends on the nature of the adsorbent and the gas at a particular temperature.
Pressure of Gas - (Measured in Pascal) - Pressure of Gas is the force that the gas exerts on the walls of its container.
Freundlich Adsorption Constant - Freundlich Adsorption Constant depends on the nature of the adsorbent and the gas at a particular temperature.
STEP 1: Convert Input(s) to Base Unit
Mass of Gas Adsorbed: 8 Gram --> 0.008 Kilogram (Check conversion here)
Adsorption Constant: 2 --> No Conversion Required
Pressure of Gas: 0.215 Pascal --> 0.215 Pascal No Conversion Required
Freundlich Adsorption Constant: 3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
m = xgas/(k*PGas^(1/n)) --> 0.008/(2*0.215^(1/3))
Evaluating ... ...
m = 0.0066769866005808
STEP 3: Convert Result to Output's Unit
0.0066769866005808 Kilogram -->6.6769866005808 Gram (Check conversion here)
6.6769866005808 Gram <-- Mass of Adsorbent

## What is Freundlich adsorption isotherm?

It is an empirical relationship between the quantity of gas adsorbed by a unit mass of solid adsorbent and pressure at a particular temperature. The relationship generally represented in the form of a curve where the mass of the gas adsorbed per gram of the adsorbent is plotted against pressure. This curve indicates at a fixed pressure, there is a decrease in physical adsorption with an increase in temperature.

How to calculate Mass of adsorbent using Freundlich adsorption isotherm using this online calculator? To use this online calculator for Mass of adsorbent using Freundlich adsorption isotherm, enter Mass of Gas Adsorbed (xgas), Adsorption Constant (k), Pressure of Gas (PGas) & Freundlich Adsorption Constant (n) and hit the calculate button. Here is how the Mass of adsorbent using Freundlich adsorption isotherm calculation can be explained with given input values -> 6.676987 = 0.008/(2*0.215^(1/3)).
