A 1.00 L sample of dry air at 25 degree C and 786 mm Hg contains 0.925 g N_2 plus other gases including oxygen, argon, and carbon dioxide. A. What is the partial pressure (in mm Hg) of N_2 in the air sample? B. What is the mole fraction and mole percent of N_2 in the mixture? (Daltons law of partial pressures) Calculate the rms speed of O_2 molecules in a tank at 21 degree C and 15.7 atm.
In a mixture of gases, how is the total pressure determined? How is the partial pressure of a gas in a mixture calculated? Determine the total pressure of a gas mixture that contains oxygen, nitrogen, and helium. The partial pressures are: Pax =20.0 kPa, Pz = 46.7 kPa, and P.. = 26.7 kPa. A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.9 kPa. If Po6.6 kPa and P2 = 23.0 kPa, what is Poz?...
