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.
The molecular weight (or, more appropriately, the molar mass) is defined by # of grams per # of moles. MW = g / mol For example: if you have 4 grams of substance and you kâ¦now the substance to be 2 moles (say, for example, the balanced chemical equation), then your MW would be 2.
