chemical composition in air

[mir]

Hi.
little clarification about something they told me:

o argon: 40 – 75 % of the volume
o co2: 25 – 55 % of volume
o nitrogen: 0 – 5 % of volume
o h2o: water vapour at 70-80%.

Is it possible that there is so much water given the percentages of other elements? That is, humidity is different as if the h2o was more... but is it a conventional thing?

Thank you.

to me is a composition:

air is composed in volume by:

* nitrogen about 76%
* oxygen about 22%
* carbon dioxide 0.04%
* traces of argon, hydrogen, neon, helium, cryptton, xenon.
* dust and water vapour as a variable percentage.
* traces of ammonia oxide, carbon, hydrocarbons, nitrogen, pollen, sand, can be found

from the comparison between different books.

Aaaarrghhh!
We're measuring different things!

75% of argon means that if you take a liter of air, you have 750ml of argon

80% moisture means that if at that pressure and temperature an air liter can contain 100ml of water at most, in your case it contains 80ml. and is called relative humidity.

This by convention. otherwise the percentage sum should do 100% and not 215%! ! !
