141. Solving a chemistry problem

A mixture of 250 ml of an aqueous solution of methyl orange with a concentration of 0.070 wt. % and 0.209 ml of mineral oil were shaken until the formation of an emulsion with an average diameter of oil droplets of 4.35 * 10-7 m. As a result of adsorption on the surface of the droplets, the concentration of methyl orange in the solution decreased to 0.038 wt. %. Calculate the adsorption G of the dye. The density of the solution is 0.9982 g / cm3, the methyl orange formula is HO3S-C6H4-N = N-C6H4-N (CH3) 2.
