Question

A Scientist who is conducting experiments with oxygen gas is investigating effective methods to store the gas wit minimal leakage. He obtains a 7-L vessel made of natural rubber with a thickness of 4 mm and a total surface area of 185000mm2. The Scientist stores the oxygen gas in this vessel at 298 K and 400 kPa.

a) State the basic assumptions you will base your calculations on.

b) Calculate the rate of oxygen loss from the vessel by mass diffusion.

c) Calculate the quantity of oxygen that would be lost through leakage by mass diffusion after one year?
