OK Christophe,

the dinitrogen must be at 30 g / mol, and the oxygen at 32 g / mol. It is true that it is neighbor. But the volume% is different: 80% N2 and 20% O2 ...

Finally, we will not quibble

I think you have a new concept there: econologiacadomia

Well that's what I say: from 21% O2 by volume we would go to 23% O2 ​​by mass ...



ps: for econologieacademia, worry, it's already done! We've been a source of inspiration for students of all kinds for a while ...
