How to solve. Please show work. Thank you! 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 1271 psi. A second 7.25-L tank holds oxygen at a pressure of 337.9 psi. The two gases are mixed in a 725-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 Number psi O Previous ® Giu up. Wismo tsceulicine check Answer 0 Next Exit Hint

Explanation / Answer

The sum of the partial pressures of the components in a gas mixture equals to the total pressure of the mixture.

Pressure of the mixture = Pressure of helium + Pressure of oxygen

= 1271 psi + 337.9 psi

= 1609 psi

Therefore, the pressure of the gas mixture is 1609 psi.
