Determine the partial pressure and concentration of Nitrogen, Oxygen, and Carbon dioxide. Given the partial pressure of Helium find for Neon.
Dry air near sea level has the following composition by volume: N2 78.08 percent: O2 20.94 percent: Ar, 0.93 percent: CO2, 0.05 percent. The atmospheric pressure is 1.00 atm. Calculate
(a) the partial pressure of each gas in atm and
(b) the concentration of each gas in moles per liter in O°C. (Hint: Because volume is proportional to the number of moles present, mole fractions of gases can be expressed as ratios of volumes at the same temperature and pressure.)
A mixture of helium and neon gases is collected over water at 28.0°C and 745 mmHg. If the partial pressure of helium is 368 mmHg, What is the partial pressure of neon? (Vapor pressure of water at 28°C = 28.3mmHg)
