Fill a balloon with oxygen. If it inflates then you have successfully proved that air has volume. If it does not inflate, grow a pair and blow harder. Then if not you know air does not have volume.
tidal volume
air has volume air has mass
Standard air can be compressed until it becomes a liquid according to the Ideal Gas Law. The density of liquid air is about 870 kilograms per cubic meter, and so theoretically you could get the compressed air down to this before it transitions to a liquid. Also, if the air were thrown into a black hole, or there is enough air to create a black hole, then theoretically the mass would be concentrated at a point in the center and have a volume of zero.
0.5 parts per million = 0.0000005, multiply by 100, and you have, 0.00005 %
type 'air' in wikipedia and there you will see that the concetration of hydrogen in air is: 0.55 ppmv (parts per milion, volumic; so there is ~half a liter of hydrogen in one million liters of air)
There is no carbon in air but in the atmosphere there is 387 PPMV (parts per million by volume) present in the form of CO2 carbon dioxide.
.0015% Neon make up 15 parts of every million in the air.
Air is about 79% nitrogen by volume.
Oxygen.
Approx 0.934% by volume.
if this is math and your asking what gas has a percent by volume 78.09 it is nitrogen
Divide 225ml by 20.9, then multiply by 100.
Carbon Dioxide!
Not even close. Argon makes up about 0.9% of our atmosphere. CO2 is closer to 400 parts per million, or 0.04%.
It is approx 1 part in 10 million or 0.00001%
