Homework Help: chemistry

Posted by sam on Thursday, August 11, 2011 at 6:04am.

Air consits of 21% oxygen, 78% nitrogen and 1% argon by volume. Calculate the partial pressures in Pa if total pressure is 1 atm.

My teacher just converted 1atm in pa and then did 21% of that for oxygen etc etc. Can you explain why she did this, is volume directly proportional to pressure? isnt it inversely proportional?

And for oxygen she just called it the oxygen mocule O2. But why? the question just said oxygen. Please someone shed some light.
