Firstly, tanks rarely provide oxygen - they usually provide simple air or other breathable gas. Pure oxygen would kill you if you breathed it deeper than about 30 feet.
Second, the average scuba tank holds the equivalent of about 80 cubic feet of gas under pressure. At the surface that would be enough to breathe off for about three hours for an everage person. But the deeper you go, the faster you consume gas because you breathe it under greater pressure.

ReneA standard Scuba tank holds around 80 cubic feet (about 2,260 liters) of compressed air, which is approximately equivalent to 2,000 liters of breathable oxygen at sea level. This amount can provide enough oxygen for an average diver for about 45 minutes to 1 hour, depending on depth and breathing rate.

Is the oxygen and helium in a scuba tank an example of a homogeneous mixture?
Yes, the oxygen and helium in a scuba tank would be considered a homogeneous mixture because they are evenly distributed throughout the tank and have uniform properties throughout.
Is the oxygen and helium in a scuba tank a pure substance?
Yes, the oxygen and helium in a scuba tank are pure substances because they consist of only one type of molecule and cannot be separated by physical means.
Is the oxygen and helium in a scuba tank a compound or heterogeneous?
The oxygen and helium in a scuba tank are considered a homogeneous mixture, not a compound or a heterogeneous mixture. In this case, the gases are mixed together uniformly, and their individual properties remain unchanged. A compound consists of two or more elements chemically bonded together, while a heterogeneous mixture would have distinct, separate components.
How much to hydro-test a scuba tank?
typically around $20-$30 depending on where you get it done, just ask around for the best price. also check the local fire station, a lot of times they know where to get it done cheap since they have to get tanks hydroed all the time
What happens when you heat an oxygen tank?
Heating an oxygen tank can cause the pressure inside the tank to increase, potentially leading to an explosion if the tank cannot withstand the pressure. This is because the heat can cause the oxygen molecules to move faster and collide more frequently with the walls of the tank, increasing the pressure. It is extremely dangerous to heat an oxygen tank and should never be done.
