Question

Quizplus · Accepted Answer

The partial pressure of atmospheric oxygen at sea level is approximately 160 mm Hg. This is because the gas constitutes approximately 21% of the total atmospheric composition, and the barometric pressure at sea level is typically around 760 mm Hg. Therefore, 21% of 760 mm Hg is around 160 mm Hg.
