Using a sea level pressure of 1000 mb and the 50% reduction rule, as well as the definition of partial pressure, calculate the partial pressure of oxygen (O2) in mb at the two heights listed below. Assume that Oz makes up 21% of the atmospheric mass at these heights. We can compare the partial pressure of Oz at any given height of interest to the partial pressure of Oz at sea level, which as we saw earlier in this lab is 210 mb. In particular, we can express the partial pressure of Oz at the height of interest as a percentage of the partial pressure of Oz at sea level. We can calculate this percentage using the following equation: partial pressure of O, at height (mb) 210 x 100 where 210 represents the 210 mb of Oz partial pressure at sea level. Note that the numerator must be the partial pressure of Oz at the height of interest in mb. You will additionally calculate this percentage for the two heights listed below. Round each answer to the nearest whole number 1. A typical cruising altitude of a jet (z = 9.5 km ASL): 1. Partial pressure of Oz at height: mb 2. Partial pressure of Oz at height expressed as percentage of sea level O2: % 2. The elevation of Mount Saint Elias (z = 5.489 km ASL): 1. Partial pressure of Oz at height: mb 2. Partial pressure of Oz at height expressed as percentage of sea level O2: %
