8. Using the constants of the Shishkovsky equation: a = 12.6•10 –3, b = 21.5, calculate the surface tension for aqueous solutions of butyric acid (at T = 273 K) for the following concentrations (kmol/m3): 0.007; 0.021; 0.05; 0.104 and build a graph in the coordinates σ = f(C); take the surface tension of water equal to σ 0 = 75.49•10 -3 N/m.
