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 6.25 L tank holds helium gas at a pressure of 1804 psi. A second 6.25 L tank holds oxygen at a pressure of 479.4 psi. The two gases are mixed in a 6.25 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. P = psi
