Adsorption of a gas a solid adsorbent follows. Freundlich adsorption isotherm. If $x$ is the mass of the gas adsorbed on mass ' $m$ ' of the adsorbent at pressure $p$. From the graph given extent of adsorption is proportional to

Adsorption of a gas ( $A$ ) on an adsorbent follows Freundlich adsorption isotherm. The slope and intercept (on $Y$-axis) of the isotherm are $0: 5$ and 1.0 respectively. What is the value of $\frac{x}{m}$, when the pressure of the gas $(A)$ is 100 atm ?
