HEY MATE
HERE'S THE ANSWER
Molecular weight will affect the rate of diffusion. All other things being constant, lighter weight molecules will move faster or diffuse faster that heavier molecules. This property could be used to separate heavier molecules from lighter weight molecules.
However, there many many other factors that can come into play with respect to diffusive processes that may offset molecular weight differences such as steric interactions (the shapes of the molecules) ionic interactions (are the molecules electrically charged) and solubility properties (how well does the molecule dissolve in the transport media.
