A solution containing two different dye molecules of different sizes (methyl blue and eosin) is kept in a glass tube. Using the knowledge of diffusion and transport phenomena, calculate the time required for the eosin molecules to diffuse to a distance of 10 cm from the source of the solution, if the diffusion coefficient of eosin is known to be 2.5 x 10^-10 m^2/s.
