Some types of packaging use two layers of membranes glued
together to control gas transmission rates. You have a balloon
comprised of polyethylene 1 mm thick and vulcanized
rubber 8 mm thick bonded together. The gas is at 2 atm pressure
inside the balloon and 0 atm outside. The temperature is 298 K.
Calculate the hydrogen flux diffusing through the balloon wall.
Ans: 2.3x10^-10 kg-mol/m^2.s
