For the adsorption of a gas on a solid,the plot of $\log(x/m)$ versus $\log P$ is linear with slope equal to

The plot of $\log \frac{x}{m}$ ($y$-axis) and $\log p$ ($x$-axis) is a straight line inclined at an angle of $45^{\circ}$. When the intercept is $\log K = 0.3010$ (where $K = 2$) and pressure is $0.3 \ atm$,calculate the amount of solute in grams adsorbed per gram of adsorbent $\frac{x}{m}$ (given $\log 3 = 0.4771$ and $\log 0.3 = -0.5229$)?

The plot of $\log(\frac{x}{m})$ against $\log P$ is a straight line inclined at an angle of $45^{\circ}$. When the pressure is $0.5 \ atm$ and the Freundlich parameter $(K)$ is $10$,the amount of solute adsorbed per gram of adsorbent will be $(\log 5 = 0.699)$ .......... $g$.
