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 of a molecule is the sum of the atomic weights of its component atoms. If a substance has molecular weight M, then M grams of the substance is termed one mole. The number of molecules in one mole is the same for all substances; this number is known as Avogadroâs number (6.022140857 Ã 10 23).
