Nitrogen - 78%
Oxygen - 21%
Carbon Dioxide - 0.04%
Noble gases - 0.96%
Showing the amount of gases in the atmosphere as percentages of dry air allows for easy comparison and analysis of the composition of the atmosphere. Since the composition of dry air is relatively stable, expressing the gases as percentages of dry air helps to standardize the data for scientific purposes.
Showing gas concentrations as percentages of dry air allows for easier comparison of the relative amounts of different gases in the atmosphere. Dry air is a consistent reference point because its composition is relatively stable, making it a convenient baseline for expressing variations in gas concentrations.
Showing the amounts of gases in the atmosphere as percentages of dry air allows for easier comparison and understanding of their relative concentrations. It provides a standardized framework that eliminates the variability that water vapor would introduce, making it simpler to analyze and compare the composition of the atmosphere.
Argon accounts for 0.93% (by volume) or 1.3% (by mass) of the earth's atmosphere.
An empty bottle has the potential to be reused or recycled. It also has air inside it, since the contents have been consumed or removed.

Hot air dries the contents. The tumble action allows the air to get to more of the surface area of the contents.

It is called relative humidity and it is expressed in percentages.
Nearly 100% of air is gas. The rest is particulate matter: dust, pollen, and also tiny organisms.
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
Percentages are percentages - simple! The marketing people have not yet come up with "new improved" percentages.
Percentages are entered as decimals. For example 12% is entered as .12. You can format a cell to display the contents as percent, if you like.
Air is made up of 78% nitrogen, 20.95% oxygen, 0.93% argon plus traces of other gases.
Carbon monoxide is one of the pollutants found in air pollution. Nitrogen oxides are another pollutant commonly found in the air.
