Homework Help: Chemistry

Posted by Avalon on Monday, March 29, 2010 at 11:27pm.

We're doing gas problems in chemsitry. I have no idea where to even begin on this problem:

Air is 20% oxygen and 80% nitrogen. What is the mass of air in an automobile tire of 19.7 L and internal pressure of 46.7 PSI at 24 degrees celsius? (That pressure is the same as the 32 PSI difference you usually measure as the tire pressure 32 PSI + 14.7 PSI. You will have to use a weighted average for the molar mass of air.)
