Answer:
There is a simple algebraic formula relating turbidity to optical properties. You do not need Mie theory. It is given in van de Hulst "Light scattering from small particles" (a nice cheap reprint from Dover Press). More easily accessible are any of the Mie calculators avaiable on the Internet, say Miecalc, these will give the exact result.
