2. Calculate the partial pressure, in atmospheres, of Oz in the dry air outside an airliner cruising at an altitude of about 35000 ft (10670 m), where the

atmoshperic pressure is 181 mm Hg. How much must the outside air be

compressed to produce a cabin pressure in which the partial pressure of

Oz is 0.200 atm? In dry air, there are 0.2085 moles of Oz in every mole of air.
