Homework Help: chemistry 106

Posted by Tanisha on Monday, March 1, 2010 at 4:20pm.

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. (Hint: Since 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) Calculate the partial pressure of each gas in atm.

(b) Calculate the concentration of each gas in moles per liter at 0C.
