1. Based on the results of measurements of the surface tension of solutions of n-hexyl alcohol in water at 12.0 °C depending on the concentration (table below), find the limiting adsorption of alcohol G∞ using a graphical method, and calculate the area occupied by 1 molecule of alcohol in a saturated adsorption layer.
С, mmol/l 0 0.62 0.81 1.25 1.72 2.50 3.43 4.90 6.86 9.80
b, mN/m 74.2 71.9 71.7 70.3 68.5 66.3 64.8 60.8 57.9 54.8
