????? gaseous exchange INSIDE the Scuba cylinder?
There is no exchange of gasses in the cylinder, that is done in the LUNGS!
A scuba Cylinder (or Tank for the americans) is a basic unit that holds compressed Gas (either AIR -21% oxygen and 79% nitrogen) NITROX (anything from 22% to 40% oxygen) Heliox (18% oxygen 40% helium rest nitrogen)
All that occurs is that the unit supplies the gas inside to a REGULATOR system fitted to the valve then to the Demand valve in the divers mouth.
No gas EXCHANGE is done here at all, only pressure restrictions.
Gas exchange happens once the Gas has entered the Lungs, there the Alveoli take the gas (mostly the oxygen) and pass it to the blood stream, and pass the Carbon Dioxide back into the lungs to breathe out.
The numbers on a scuba tank reveal 3 things. Serial no. of the tank. Type metal. and the current hydro date.

The empty weight of a 100 cubic foot steel SCUBA tank is approximately 33lbs.
Depends on the size of the tank.
Depends on the size of the tank.
A scuba tank typically holds about 11 liters of air at atmospheric pressure.
I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.
the silly answer is you can store anything in a scuba tank that you can get in it!!. BUTthe serious answer is scuba tank were designed for compressed air and nothing else... using a scuba tank for natural gas is like driving around with a bomb in your car!!, the valves and collars of the bottles are not strong enough if there was a crash
No.
its the scuba tank on the swimming guys back.
You can use a scuba tank, but that is it.
Different scuba gear types weigh different amounts. The oxygen tank is the heavy part of the scuba diving gear.
