Air: 78% N2 21%O2 1% Ar by volume
What is the density of this air at 1.3 atm and temperature 263K?
Please walk me through the steps to solve this. I don't know what to do with problems that give percents like that.
I will vote on best answer.

I will pass the ball and let you finish the play
ave "molecular weight" of air = .78*28 +.21*32 +.01*40 ====AMW
----------------
molar density 1mole/22.4 L * 1.3/1 * 263/273 = MD moles/liter
------------
density : MD moles/liter * AMW g/mole = answer in g/liter
I have confidence you can plug and chug
