The barometric pressure at sea level is 760 mm Hg.Because of the relatively high altitude of Antonito, Colorado, the town has a normal barometric pressure of about 600 mm Hg.The partial pressure of O₂ in Antonito's air is therefore approximately _______ mm Hg.

Question

Quizplus · Accepted Answer

The partial pressure of oxygen in air is approximately 21% (0.21) of the total atmospheric pressure. Therefore, in Antonito, the partial pressure of oxygen would be (0.21) x 600 mm Hg = 126 mm Hg.

The Barometric Pressure at Sea Level Is 760 Mm Hg
