6. Find the surface tension of aniline, if the following data were obtained using Traube´s stalagmometer: the number of aniline droplets 42; the aniline density ρ = 1.4 • 103 kg / m3; number of drops of water 18; the water density is ρ0 = 1.0 · 103 kg / m3; surface water tension σ0 = 73.26 • 10-3 N / m; the temperature of the experiment is T = 288 K.
