Problem 1 (Tosun): Modified Atmosphere Packaging (MAP') is the process of adjusting the gas composition in the headspace of food packages to prolong shelf life. The gas mixture usually consists of carbon dioxide, nitrogen, and oxygen. Meat packages, for example, contain high concentrations of carbon dioxide to prevent the growth of microorganisms by suppressing microbial activity. Consider one-dimensional diffusion of carbon dioxide through a new polymeric film 270m thick under steady conditions. The partial pressure of carbon dioxide inside the package is 0.6atm and outside it is 0.03atm. If PM=19 barrer, estimate the molar flux of carbon dioxide
