Homework Help: Chemistry

Posted by Anonymous on Sunday, January 9, 2011 at 10:58am.

It turns out that the Van Dar Waals constant b is equal to four times the total volume actually occupied by the molecules of a mole of gas. Using this figure, calculate the fraction of the volume in a container actually occupied by Ar atoms:
a) at STP
b) at 100 atm pressure and 0 degrees Celsius

((Assume for simplicity that the ideal-gas equation still holds.))

Ar

a= 1.34
b = 0.0322

I'm extremely confused about this question, are they asking for the volume when they state fraction of the volume.
