46. Solving a chemistry problem

2. Using the laws of light scattering in accordance with the Rayleigh theory and the attenuation of the light flux in accordance with the Bouguer-Lambert-Beer law, calculate the radius of the divinylstyrene latex particles from the results of measuring the optical density D in
Latex concentration, g/l 0.2
λ, nm 400
D 0.347
The density and refractive index of the dispersed phase are 0.945 g/cm3 and 1.653; the refractive index of water is 1.333.
