5.3. Determine the surface tension and surface activity of isoamyl alcohol at the boundary of an aqueous solution - air at 273 K for aqueous solutions of alcohol with a concentration (kmol / m3): 0.016; 0.020; 0.024; 0.028; 0.032. The constants of the Shishkovsky equation: a = 21.12 * 10-3 and b = 42.0. The surface tension of water is 75.64*10-3 N/m.
