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?

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
