- Using data from Table 1, determine the volume fraction of pores in silica gel (small-pore type) filled with adsorbed water vapor when its partial pressure is \( 4.6 \mathrm{~mm} \mathrm{Hg} \) and the temperature is \( 25^{\circ} \mathrm{C} \). - In addition, determine whether the amount of water adsorbed is equivalent to more than a monolayer, if specific surface area of the silica gel is \( 830 \mathrm{~m}^{2} / \mathrm{g} \). - The area of an adsorbed water molecule is given by \[ \alpha=1.091\left(\frac{M}{N_{A} \rho_{L}}\right)^{2 / 3} \]
