How valuable is oxygen in money?
Oxygen is free. Wherever you go, there is an unlimited supply
all around you.
Nobody has access to more or less oxygen than anybody else has,
and nobody
ever has to pay for oxygen.
What you DO pay for is to have someone compress (or liquify) the
oxygen,
stuff it into a suitable container for you, and deliver it to
you. Prices depend
on the pressure in the container, the volume inside the
container, and the
purity of the oxygen in there ... the oxygen you need for
respiratory therapy
will be different and more expensive than the oxygen you use for
welding.
