The mass of gas adsorbed, $\displaystyle x$, per unit mass of adsorbate, $\displaystyle m$, was measured at various pressures, p. A graph between $\displaystyle \log \frac{x}{m}$ and $\displaystyle \log p$ gives a straight line with slope equal to $\displaystyle 2$ and the intercept equal to 0.4771. The value of $\displaystyle \frac{x}{m}$ at a pressure of $\displaystyle 4$ atm is: (Given $\displaystyle \log 3=0.4771)$
