The surface pressure of n-hexyl alcohol at 285 K is known depending on its concentration in an aqueous solution:
c * 104, mol/l 6.2 8.1 12.5 17.2 25 34.3 49.0 68.6 98
n *103, N/m 2.3 2.5 3.9 5.7 7.9 9.4 13.4 16.4 19
Calculate the amount of adsorption, the area per mol, and the area occupied by one alcohol molecule in a dense monolayer using the Gibbs equation.
