4. Given a dispersed system with a mass of the dispersed phase m, a density of the dispersed phase ρ, with particles of the dispersed phase of a certain shape and size: r is the radius of the ball, I is the length of the edge of the cube.
1. Calculate the dispersion of the system D and the specific surface area Ssp.
2. Calculate the parameters of a single particle of the dispersed phase: volume V0, surface S0, mass m0
3. Calculate the total surface of all particles S and the number of particles N in the dispersed system.

Dispersed phase Dispersion medium Particle shape g(|), m ρ, 10-3 kg/m3 m, kg
