The atmospheric pressure varies with height according to the following barometric formula The atmospheric pressure varies with height according to the following barometric formula:P = Pgas x e (-gMh/RT)Pgasis the partial pressure of the gas at atmospheric pressure and sea level. M is the molecular mass of the gas, his the height in meters and g= 9.8 m.s-2.Assuming that air is 20% O2 and 80% N2 at sea level and the atmospheric pressure is 1.00 atm, what is the partial pressure of O2at a height of 46,200 feet? The temperature at this altitude is-73.0oC. Note: 1 yard = 3 feet and 1 m = 1.1 yards.
