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.
Molecular Weight. Molecular weight is the collection of weights of all the atoms in a molecule. The SI unit of the molecular weight is g mol. This gives the amount of the atoms/molecules/compounds present in one mole of the substance. In other words, it is the mass of Avogadro number of atoms/molecules or compounds.
