72. Solving a chemistry problem

2. Calculate the turbidity in cm-1 of the latex dispersion, if the radius of the particles is 2.8∙10-6 cm, the weight concentration is 0.0002 g/cm3, the density of the particles is 0.945 g/cm3, the refractive index of the particles is 1.655, the medium is 1.333. Carry out the calculation for the wavelength of light 4∙10-5 and 6∙10-5 cm. Also determine the optical density of the system for a beam 10 cm long.
