602. Silica sol turbidity (SiO2, brand name Ludox) measured as a function of concentration with the following results:

s*102, g/cm3 0.57 1.14 1.7 2.3
t*102, cm–1 1.59 2.97 4.25 5.36
Determine from these data the molar mass of the particles and then from the radius, assuming a density of silica of 2.2 g/cm3. Optical constant of the device H=4.08*10-7 mol*cm2/g2.
