6. Knowing the surface pressure of n-hexyl alcohol at 285 K depending on its concentration in an aqueous solution:
c*104, mol/l 6.2 12.5 17.2 25 34.3 49
П*10, N/m 2.3 2.5 3.9 5.7 7.9 9.4 13.4
calculate the adsorption value, the area per 1 mole, Sm and the area occupied by one molecule of alcohol in a dense monolayer so, using the Gibbs equation.
