(a) Find the average time (in s) required for an oxygen molecule to diffuse through a 0.205 mm thick tear layer on the cornea. (Assume the diffusion constant of oxygen through tears is 2e-9 m²/s.) (b) How much time (in h) is required to diffuse 0.45 cm³ of oxygen to the cornea if its surface area is 1.1 cm²?
