Question

Calculate the mole fraction of oxygen in the air. If air contains 18.0 g oxygen gas at 285 K at 1.20 atm, what is the volume of air?

Table showing the composition of dry air by volume, highlighting nitrogen, oxygen, argon, and carbon dioxide.

Accepted Answer

χ_O2 = 0.21, V_air = 52.2 L

Answer

χ_O2 = 0.17, V_air = 52.2 L

Answer

χ_O2 = 0.17, V_air = 11.0 L

Answer

χ_O2 = 0.21, V_air = 11.0 L
