A sample of air contains 78.8% nitrogen, 20.94% oxygen, 0.05% carbon dioxide, and 0.930% argon by volume. How many molecules of each gas are present in 1.00 L of the sample at 35 degrees C and 1.00 atm?

The percentages don't add to 100%. Please check the post for accuracy.
I'm sorry, that should read 78.08% nitrogen
You will have 0.7808 L nitrogen. How many moles is that? PV = nRT
Then n x 6.022 x 10^23 = # molecules.
The others are done the same way.
