If 96.5 mol of an ideal gas occupies 97.5 L at 93.00 °C, what is the pressure of the gas? 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 1563 psi. A second 7.25-L tank holds oxygen at a pressure of 415.6 psi. The two gases are mixed in a 7.25-L tank....
