Diffusion WS Name 2. Methylene chloride is a common ingredient of paint removers. Besides being an irritant, it also may be absorbed through skin. When using this paint remover, protective gloves should be worn. If butyl rubber gloves (0.04 cm thick) are used, what is the diffusive flux of methylene chloride through the glove? Diffusion coefficient in butyl rubber D = 110 x 10-8 cm²/s. Concentrations on the outside and inside surfaces of the glove are C₁ = 0.44 g/cm³, C₂ = 0.02 g/cm³. wing ve the 12

The partial pressure of oxygen in the lungs is about 150 mm of Hg. (The partial pressure is the pressure of the oxygen alone, if all other gases were removed.) This corresponds to a concentration of 5.3 × 1024 molecules per m3. In the oxygen-depleted blood entering the pulmonary capillaries, the concentration is 1.4 × 1024 molecules per m3. The blood is separated from air in the alveoli of the lungs by a 1-μm-thick membrane. What is the rate of transfer of oxygen to the blood through the 5 × 10-9 m2 surface area of one alveolus? Give your answer in both molecules/s and μmol/s. Assume The diffusion coefficient for oxygen in tissue is 2 × 10-11 m2/s. What is the same rate of transfer in μmol/s.
