96. Solving a chemistry problem

Consider applying the Bouguer-Lambert-Beer equation for iron hydroxide hydrosols using data on the attenuation of monochromatic light (h = 500 nm) by these disperse systems:

Sol concentration, wt % 0.20 0.10 0.08 0.04 0.02
Layer thickness, mm 2.5 2.5 2.5 5.0 5.0
Transmission, % 1.7 11.8 18.6 18.2 43.0

Determine what proportion of light will be scattered by 0.02% sol in a 30 mm cuvette.
