No idea on the O2 bottle...it's not stored as a liquid.

O2 can be calculated from the volume stored in the tank and boyles law.

They dispense 1.1 cubic feet of gas at standard tmp/pressure.

On another thread someone mentioned about 400 PSI. This is about right for the volume stored.

They are filled to around 400 psi. You should know the difference between oxygen and air before doing something like this. Oxygen has 5 times the oxygen content of air so things will burn much more rapidly, violently and easily. Many oils will spontaneously combust in it's presence. A google search on oxygen hazards would be a good idea first.
