Solving a chemistry problem 000 032

1. Based on the data on the dependence of surface tension (σ) of solutions of acetic acid in water, construct the dependence of acid adsorption in the Guggenheim version on its mole fraction.
C, g/l 0 0.01 0.1 0.5 1.0
σ, mJ/m2 72.8 70.0 68.9 61.7 57.3
The solution is considered ideal, and the density at t = 20 °C is taken equal to 1000 kg/m3.
