So far, I have used PV=nRT. I set V=1. I found that n = .1226 moles. I multiplied that by avogadros number and got

7.38 * 10 ^ 22 molecules. Is this correct?

**DrBob222**, Wednesday, November 12, 2008 at 9:39pmHow do you know V = 1? If you set V = 2 (or 3, or 4 or 5) will that change the number of molecules.

You do not know the volumes of the tires except that they are all the same. "V = 1" (an arbitrary unit of volume) cannot give you a specific number of moles or number of molecules. However how do the numbers of molecules for each gas compare to each other?
