At a temperature of $180K$, O₂ gas adsorbs on a Pt surface following the Freundlich adsorption isotherm. The following experimental data is obtained:

where P is the partial pressure of gas and $x/m$ is the mass of gas adsorbed per gram of platinum. Calculate the millimoles of O₂ adsorbed per gram of platinum at 4 bar pressure and $180K$.
