The earth's atmosphere at sea level.
78% nitrogen 20% oxygen and 2% other inert gases.
air is made up of some gases. i.e. it's made up of hydrogen, nitrogen, and mixture of other gases. but the most common is it is made up of nitrogen-78%, oxygen-21%, and other gases-1%air is made up of different gases such as oxygen, carbondioxide, nitrogen and noble gases.
You need two quantities to have a per cent - one of them as a percent[age] of the other.
In the air around us there is 78% nitrogen 21% oxygen 1% other gasses
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
The composition of air is usually sated as a dry composition (without water vapour). About 21% is oxygen. The rest is mostly Nitrogen (78%) and Argon (1%). Carbon Dioxide at 300ppm is the next largest with other gases at trace amounts
Those percentages closely match the composition of Earth's atmosphere at sea level. The atmosphere is made up of mostly nitrogen (around 78%) and oxygen (around 21%), with trace amounts of other gases like carbon dioxide (around 0.04%).
The earth is actually composed of a total of 90 chemical elements. 81 of them have at least one stable isotope.
Nitrogen, with oxygen making up most of the remaining 20 percent. Other gases such as argon, carbon dioxide, and trace amounts of other gases make up the rest of the Earth's atmosphere.
The atmospheric gas of Earth consists of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.03 percent carbon dioxide, with hydrogen, water, ozone, neon, helium, krypton, xenon, and traces of other elements making up the remaining 0.07 percent.
Approximately 79% nitrogen and 21% oxygen I thing more accurately it is more like 20.5% oxygen, and the rest is nitrogen and other gasses. Carbon dioxide only makes up around 0.03% of the air
we have 21% of oxygen , 78% of nitrogen and 1% of the other gases and that's what make the earth's atmoshere by: nadia
0.93% argon, 0.04% carbon dioxide, and small amounts of other gases including water vapor.
This gas is oxygen - 20,946 %.
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.
The moon's crust composition is similar to the Earth's, but the moon's mantle contains a higher amount of iron. While the moon's crust is composed of 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, and trace amounts of other elements. The Earth's crust is made up of 46.6 percent oxygen, 27.7 percent silicon, 8.1 percent aluminum, 5.1 percent of iron, 2.1 percent magnesium, and other elements.
78% nitrogen 21% oxygen 1% other gases like argon, carbon dioxide etc.
