Oxygen needs to be compressed in a diver's tank to increase the amount of oxygen that can be stored in the tank. Compressing the gas allows divers to carry enough oxygen to sustain them while underwater for a longer period of time without the tank becoming too large and unwieldy.
Usually AIR, which is 21% Oxygen and 79% Nitrogen...BUT!!!! It could have been used for Nitrox, which is elevated Oxygen, If you dont KNOW for sure what is in it, DUMP the gas and refill the cylinder.
Nitrogen is used in air tanks to dilute the oxygen content, reducing the risk of oxygen toxicity for the divers or miners. This helps prevent certain health issues that can arise from breathing high levels of oxygen under pressure, such as seizures or respiratory problems.
To empty an oxygen tank, you need to open the cylinder valve and allow the oxygen to release until the tank is empty. Make sure to do this in a well-ventilated area and follow safety guidelines provided by the tank manufacturer or healthcare provider. Once empty, properly dispose of or return the tank according to regulations.
If it is supposed to be an oxygen tank, the amount of oxygen remaining is usually determined by weighing the tank (on some scales with enough capacity to measure such a weight) and then subtracting the weight of the empty tank (the tare weight) which should be recorded before the tank was filled. If it is a matter of testing whether any oxygen is in a tank that contains a mixture of substances, then you'd probably need to take a sample and run it through something like a mass spectrometer or a gas chromatograph calibrated to look for that substance.
The distance you can go before running out of oxygen depends on factors like your level of physical activity and the volume of oxygen in your tank. On average, a scuba diver with a standard tank can go from 30 minutes to an hour at recreational depths before running out of oxygen. It is essential to monitor your oxygen levels and plan your dive accordingly.

they need to know how long they can be underwater, and how deep they can go with the air in the tank.
The simple answer is ... you don't. A majority of scuba dives use compressed air in the cylinders. Therefore you don't need "oxygen" cylinders. HOWEVER, if you are a diver that is diving on Nitrox, in which divers change the amount of oxygen vs nitrogen in their air, then your tank needs to be "oxygen clean" because you are putting oxygen in first, then nitrogen.
An aqualung is a piece of equipment consisting of an oxygen tank and breathing apparatus used by divers to allow them to breathe underwater at depth.

They don't breathe normally on their own.They have to use pressure regulators to breathe naturally, overcoming the extreme pressure deep underwater.A snorkel and oxygen tank help the divers breathe when they are underwater.
yes, basically you're just saying what scuba-divers do

The use of an oxygen analyzer would be advised. Most nitrox and technical divers have one.
Divers (and others) call the compressed air cylinders used by divers tank(s) or SCUBA tank(s).
