The graph of $\log \frac{x}{m}$ vs $\log p$ for an adsorption process is a straight line inclined at an angle of $45^{\circ}$ with an intercept equal to $0.6020$. The mass of gas adsorbed per unit mass of adsorbent at the pressure of $0.4 \ atm$ is $......... \times 10^{-1}$ (Nearest integer). Given: $\log 2 = 0.3010$.
