A 1-mm-thick BCC iron foil is used to separate a region of high nitrogen gas concentration of 0.1 at% from a region of low nitrogen gas concentration at 710 C. For the diffusion of nitrogen through BCC iron Q = 76.6 kJ/mol and Do = 0.0047 cm/s. For BCC iron, there are two atoms per unit cell with an axial length of 2.86610-10 m. If the flux of nitrogen through the foil is 1012 atoms, what is the difference of nitrogen concentration between the high cm concentration region and the low concentration region? (Express your answer to three significant figures.)
