It turns out that the van der Waals constant b equals four times the total volume actually occupied by the molecules of a mole of gas. Using this figure, calculate the fraction of volume in a container actually ocupied 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.)

thanks for any help =]

a gas
