Is ordinary air about 21 percent oxygen and 78 percent nitrogen?
it contains 78% nitrogen 21% oxygen and 1% Argon in clean air. However There are more chemicals in that 1 remaining percent such as Helium, Carbon Dioxide, Methane, etc. But the Majority of that 1% is Argon therefore we class the 1% as Argon - Matthew Pote
