I can't figure this question. I'm looking through my book but I'm just more confused now.
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 hold helium gas at a pressure of 1554 psi. A second 6.25L tank holds oxygen at a pressure of 413.1 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.

-
For mixtures with ideal gas behavior Dalton's law can be used - where each component of the mixture can be treated independently and the total pressure is the sum of the partial pressures of each component. Since the temp does not change and the volume of the mixing tank is the same as that of each of the two gasses the pressure of He in the mixing tank is 1554 psi, the pressure of O2 in the mixing tank will be 413.1 psi and the total pressure will be 1554 + 413.1 = 1967 psi
