The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. Calculate the number of kilograms of hydrogen that pass per hour through a 2.8 mm thick sheet of palladium having and area of 0.72 m^2 at 500 C. Assume a diffusion coefficient of 7.8 x 10^-8 m^2/s, that the concentrations at the high- and low- pressure sides of the plates are 3.4 and 0.58 kg/m^3 of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.

We're told oxygen is the most common element in the Earth's solid crust. But how much oxygen is there? Let's compare to the amount of oxygen in the Earth's atmosphere, like this: • The most common minerals in the Earth's crust are feldspars, and anorthite (CaAl,Si₂O) is a typical feldspar. Let's assume the entire crust is made of anorthite, with a density of 2.8 g/cm³. • The radius of the Earth is 6371. km and let's say the crust is the upper 75.0 km of it. • Let's model the Earth's atmosphere as a layer on top of the Earth about 100. km thick with an average density of 0.99 g/m³, and which is 23.1% oxygen by mass. Use this information to calculate the ratio of the mass of oxygen in the Earth's atmosphere to the mass of oxygen in the Earth's crust. Round your answer to 2 significant digits.

An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295k and volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1 mL atm K-1 mol-1.
