100. Solving a chemistry problem

Determine the phase interface in the system, the number of particles in it, the excess energy if it is an emulsion of 80 g of benzene with a surface tension of 0.03 N/m3, a density of 860 kg/m3, and a particle radius of 2 µm. Determine also the radius of the particles, which would correspond to a 10% increase in vapor pressure over a flat surface.
