Answer:

309 liters

A wonderful constant within the gas laws states that 1 mole of any gas occupies 22.4 liters at STP.  ANY gas.  Make that into a conversion factor you can use at your next social gathering if you want to annoy some friends:

Use that factor to find the answer:

(13.8 moles)(22.4L/1 mole) = 309 liters
