A sheet of palladium having a cross-section area of 0.15 m^2 and 5 mm thick is used as steady state diffusion membrane for hydrogen. Calculate the mass of hydrogen being purified per hour, if the concentration gradient (difference in concentration on both sides of membrane) of hydrogen on high pressure side is 1.5 kg/m^3. The diffusion coefficient hydrogen in palladium is 1 * 10^-8 m^2/s.
