If you mean the rough percentages, I believe it's 78% Nitrogen 21% Oxygen and 1% Other mixed gases.

The gases are normally separated by cooling air. The different components liquify at different temperatures. Water first, then carbon dioxide, followed by oxygen (minus 180 C) and nitrogen (minus 196 C). The hardest to liquify is helium at about minus 270 C.

The liquid gases are transported and stored in large metal vacuum insulated flasks.

well, that depends on what you really mean with your question.. u ask the ration between the gases or the force that keep them away?
