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.
diffusion coefficient the number of milliliters of a gas that will diffuse at a distance of 0.001 mm over a square centimeter surface per minute, at 1 atm of pressure. The diffusion coefficient for any given gas is proportional to the solubility and molecular weight of the gas.The diffusion coefficient for oxygen is 1.0, for carbon dioxide it is 20.3, and for nitrogen it is 0.53. The diffusion capacity of a gas varies directly with the diffusion coefficient.he number of milliliters of a gas that will diffuse at a distance of 0.001 mm over a square centimeter surface per minute, at 1 atmosphere of pressure. The diffusion coefficient for any given gas is proportional to the solubility and molecular weight of the gas.
