(B) According to the Freundlich adsorption isotherm,$\frac{x}{m} = k \cdot p^{1/n}$.Taking $\log$ on both sides,we get $\log (\frac{x}{m}) = \log k + \frac{1}{n} \log p$.Comparing this with the equation of a straight line $y = mx + c$,the slope is $\frac{1}{n} = \tan 45^\circ = 1$,so $n = 1$.The intercept is $\log k = 0.3010$. Since $\log 2 = 0.3010$,we have $k = 2$.Substituting these values at $p = 0.5 \ atm$,we get $\frac{x}{m} = 2 \times (0.5)^1 = 1.0 \ g$.
