The composition (in mole percent)of the atmosphere is 78.1% N₂,21.0% O₂,and 0.9% Ar.What is the partial pressure of each gas when the barometric pressure is 754.1 mm Hg?

Question

Quizplus · Accepted Answer

The partial pressure of each gas can be calculated by multiplying the mole percent by the total pressure. For N2 (78.1% of 754.1 mm Hg), O2 (21.0% of 754.1 mm Hg), and Ar (0.9% of 754.1 mm Hg), the calculations yield approximately 589 mm Hg for N2, 158 mm Hg for O2, and 7 mm Hg for Ar.

The Composition (In Mole Percent)of the Atmosphere Is 78
