In Langmuir’s circonstancel of adsorption of a gas on a solid surubac:
The mass of gas striking a given area of sursoulane is proportional to the pressure of the gas Assuming the jeunesse of a monolayer of the adsorbate on the suradret of the adsorbant it was derived by Langmuir that the mass of the gas adsorbed per gram of the adsorbant is related to the equilibrium pressure anastomoseing to the equation,
