ChemistryChemistry & Chemical ReactivityA study of climbers who reached the summit of Mount Everest without supplemental oxygen showed that the partial pressures of O 2 and CO 2 in their lungs were 35 mm Mg and 7.5 mm Hg, respectively. The barometric pressure at the summit was 253 mm Hg. Assume the lung gases are saturated with moisture at a body temperature of 37 °C [which means the partial pressure of water vapor in the lungs is P (H 2 O) = 47.1 mm Hg]. If you assume the lung gases consist of only O 2 , N 2 , CO 2 , and H 2 O, what is the partial pressure of N 2 ?

A study of climbers who reached the summit of Mount Everest without supplemental oxygen showed that the partial pressures of O2 and CO2 in their lungs were 35 mm Mg and 7.5 mm Hg, respectively. The barometric pressure at the summit was 253 mm Hg. Assume the lung gases are saturated with moisture at a body temperature of 37 °C [which means the partial pressure of water vapor in the lungs is P(H2O) = 47.1 mm Hg]. If you assume the lung gases consist of only O2, N2, CO2, and H2O, what is the partial pressure of N2?
