1. The purification of hydrogen gas by diffusion through a palladium sheet was discussed in Section Compute the number of kilograms of hydrogen that pass per hour through a 5-mm-thick sheet of palladium having an area of 0.25 m2 at 500°Č. Assume a diffusion coefficient of 1.0 × 10-8 m2/s, that the concentrations at the high- and low-pressure sides of the plate are 2.4 and 0.6 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.

Carbon tetrachloride (CC14) is diffusing through benzene (C6H6), as the drawing illustrates. The concentration of CCl4 at the left end of the tube is maintained at 1.95 x 10-2 kg/m3, and the diffusion constant is 20.4 x 10-10 m²/s. The CCl4 enters the tube at a mass rate of 4.52 x 10-13 kg/s. Using these data and those shown in the drawing, find (a) the mass of CCl4 per second that passes point A and (b) the concentration of CCl4 at point A.

The label on a tank of gas of unknown origin had been lost. To determine its identity (molecular weight) a certain volume of it took 7.155 seconds to effuse through a porous partition. Under identical conditions, CCl 4 effused through the hole in 62.50 seconds. What is the molar mass of the unknown gas? Remember that effusion rate and time are inversely proportional to each other.
High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 1.45x107 Pa, what is its running pressure in torr? Express the pressure numerically in torr. ► View Available Hint(s) 1.45x107 Pa = VE ΑΣΦ ? torr
