Hello Ariana! Molecular weight and diffusion are inversely proportional; the greater the molecular weight, the slower the rate of diffusion. In fact, certain molecules can never pass through membranes, thus protecting the cell. I am not sure I understand your theory and second question.
From the Mark-Houwink equation the relationship among the molecular weight and viscosity are given below. Where is the intrinsic viscosity, is Molecular weight, and are constants for a particular polymer solvent system. If we know the and values for a given polymer solution the intrinsic viscosity and molecular weight can be calculate using the above equation.
