Ethyl alcohol is diffusing into an alcohol-water solution at 18°C. The concentration of alcohol in the bulk of the solution is negligible, while that at the surface of the solution is 0.12 g/cc. The film thickness is 0.15 cm and the diffusivity is 1 x 10-5 cm2/s. Calculate mass of alcohol in pounds diffusing through 100 ft2 of interface per hour.
