11. Solving a chemistry problem

1. Determine the number of particles, the phase separation surface, the excess energy of the system, the excess pressure of the liquid in a separate drop, and the excess pressure of the saturated vapor of particles of the dispersed phase, if the system is a drop of mercury with a total mass of 15 g with a surface tension of 0.475 N/m, a substance density of 13500 kg/m3 and a particle radius of 0.02 µm. Saturated vapor pressure over a flat surface is 0.4 Pa.
