Heliox is a helium‑oxygen mixture that may be used in scuba tanks for divers working at great depths. it is also used medically as a breathing treatment. a 7.25 l tank holds helium gas at a pressure of 1906 psi. a second 7.25 l tank holds oxygen at a pressure of 506.7 psi. the two gases are mixed in a 7.25 l tank. if the temperature remains the same throughout the process, what is the pressure of the gas mixture in the tank? assume ideal gas behavior.

2412 psi is the pressure of the gas mixture in the tank.

Explanation:

Pressure of the helium gas = 1,906 psi

Volume of the helium gas = 7.25 L

Pressure of the oxygen gas = 506 psi

Volume of the oxygen gas = 7.25 L

After mixing both gases in a container with volume 7.25 L at with constant temperature.

Since, the temperature and volume remained constant, pressure becomes directly dependent on moles of gases.So, when we mix gases together the moles of gases will also add and along with that pressure of individual gas will also get added to give total pressure of the mixture in a tank.

Total pressure = pressure(Heluim)+pressure(oxygen)

2412 psi is the pressure of the gas mixture in the tank.

i don't know that i agree with that but what's the question ?

reserve is the answer
