5. Data on the adsorption of butanol at the interface are given in the table:
conc, mol/l 0 0.06 0.125 0.25 0.5
ads, mol/m2 0 3.8*10-6 5.3*10-6 6.3*10-6 7*10-6

If the density of butanol is 820 kg/m3, find the geometric dimensions of the butanol molecule, as well as the ratio between the concentration of butanol in the surface layer with a thickness of one molecule (in mol/l) and the concentration of butanol in the volume of the solution for all concentrations indicated in the table.
