Simple linear math; no "calculus", etc. Just divide the "new" pressure by
the 2080 psi, and multiply the result by 219, and that is the new contents.
Or, to put it another way, Contents = (beginning content)/(beginning
pressure) x (new pressure).

I THINK I did that right... Anyway, if you had 219 cu.ft. at 2080 psi, it
would be 53.4 cu.ft. at 500 psi. Yeah. Simple. Duh...
