100. Solving a chemistry problem

Calculate the total and specific phase separation surface of the SiO2 hydrosol, the average particle diameter of which is 120•10-9 m, and their density  = 2.65•103 kg/m3 (given the answer in m-1 and m2/kg). Calculate the surface energy if the surface tension of silicon oxide is 725∙10-3 J/m2
