To find the partial pressure of oxygen, we first need to calculate the total pressure of the air in the airplane cabin using Dalton's law of partial pressures. Given that the atmospheric pressure at 13000 ft altitude is 650 mm Hg, the partial pressure of oxygen can be calculated as 21% of this total pressure since oxygen constitutes 21% of the air. Thus, the partial pressure of oxygen on the plane is: 0.21 * 650 mm Hg = 136.5 mm Hg.
2500 mm is equivalent to 2.5 meters.
35 cm equals 350 mm, because there are 10 millimeters in one centimeter.
6.5 cm is equal to 65 mm. This conversion is based on the fact that 1 cm is equal to 10 mm.
270 mm is equal to approximately 10.63 inches.
