If N₂ Gas Comprises 79% of Atmospheric Air at Sea

Question

If N2gas comprises 79% of atmospheric air at sea level, what is the partial pressure of N2?
A) about 300 mm Hg
B) about 500 mm Hg
C) about 600 mm Hg
D) about 700 mm Hg

Accepted Answer

The total atmospheric pressure at sea level is approximately 760 mm Hg. Since N₂ makes up 79% of the atmosphere, its partial pressure is 0.79 * 760 mm Hg ≈ 600 mm Hg.
