# A gas mixture has 2 atm He, 4.8 atm Xe, and 1.9 atm O_2. Which gas takes up the most volume in a total of 456 mL?

So, given the above, to ask which gas occupies the most volume is a non-sequitir. All the gases occupy an equal volume, and, as stated, this volume is $456 \cdot m L$. The total pressure is of course $\left(2 + 4.8 + 1.9\right) \cdot a t m$, but this is not what the question asked.
