a) Diffusion takes place across the following membrane, in which the membrane has a surface area of 100cm and a thickness (Ax, or dx) of 0.08cm. If 48g of a gas diffuse through this membrane over 48hr, what is the Flux of the system? ( Ax 0.08cm Area 100cm 16000000 50000000 0.29 313, what is b) Assuming this system is in steady-state diffusion, determine the Diffusion Coefficient of the system if the concentrations on each side of the membrane are 0.55g/cms and 0.15g/cms.
