78% nitrogen gas
21% oxygen gas
Approximately 20 percent of the Earth's atmosphere is made up of oxygen.
Nearly 1% of the Earth's atmosphere is made up of water vapor.
This means that the purity is 99%, 99 parts out of 100 are butyric acid.
Neptune (NovaNet) There's something wrong here. Neptune is mainly a hydrogen atmosphere. Earth is the planet with a mainly nitrogen atmosphere, but the coldest is Neptune.

nitrogen
Earth's atmosphere is roughly 78% Nitrogen & 21% Oxygen.
Nitrogen and oxygen make up 99% of Earth's atmosphere.
Tropospere & Stratosphere
Hydrogen and helium make up 99 percent of Jupiter's atmosphere. These two gases are the most abundant elements in the planet's composition.
The percent of the atmosphere made out of carbon dioxide is 0.038.
It is 99 percent water and 1 percent fiber
99%
A 99% solution of alcohol will self-dilute by absorbing moisture from the atmosphere unless completely sealed.
Over 99 percent of the atmosphere in pure dry air is composed of nitrogen and oxygen, with nitrogen making up about 78 percent and oxygen around 21 percent. The remaining 1 percent is made up of trace gases such as argon, carbon dioxide, and neon.
99 percent of air is made up of air pollution from motor vehicles.
The nitrogen and oxygen in Earth's atmosphere together account for a speck more than 99% of it..
