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 2206 psi. A second 7.25 L tank holds oxygen at a pressure of 586.5 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...
