Question

Sapling Learning 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 5.25-L tank holds helium gas at a pressure of 1586 psi. A second 5.25-L tank holds oxygen at a pressure of 421.5 psi. The two gases are mixed in a 5.25-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. Number

Answer 1

Under equal temperatures and Volume, assuming that ideal gas behavbiour holds, thenpressures become additive. The total pressure is simply the sum of the individual pressure = 1586 + 421.5 = 2007.5 psi
