How would I figure out the volume of gas inside of a 200 size (9" x 51") of NH3 (ammonia) @ 114 psia?

Sorry, but I don't quite understand you here.

You want to find the volume of ammonia in the cylinder?

Well, the volume of the ammonia fills the cylinder, meaning that the cylinder has the same volume as the ammonia.

The equation for ideal gas is:



If you have the pressure, the temperature and the amount of moles (or mass) of ammonia, then you can find the volume of ammonia.

You may have to do it by weight since ammonia deviates substantially from the ideal gas equation. You need to subtract the tare weight of the cylinder from the total weight in order to get the weight of ammonia.
