The answer to this question is Argon.
The gas with a percent volume of 78.09 is nitrogen (N2).
if this is math and your asking what gas has a percent by volume 78.09 it is nitrogen
No, mole percent and volume percent are not necessarily equal for a gas. Mole percent is the ratio of the moles of a gas to the total moles of all gases in a mixture, while volume percent is the ratio of the volume of a gas to the total volume of all gases in a mixture. The two can be equal only if the gases have the same molar volume at the given conditions.
water vapor
Oxygen is the gas that accounts for about 20 percent of Earth's atmosphere.
It accounts ofr 0.934% by volume, of the earth's atmosphere.
Carbon dioxide is the gas in dry air that typically comprises approximately 0.036% of the total volume.
WATER VAPOR. It is the lightest gas on Earth and varies in volume (0.0 to 4.0) because of amounts.
If the temperature of a gas is reduced by 25%, its volume decreases proportionally if the pressure and quantity of gas remain constant. This is known as Charles's Law, which states that the volume of a gas is directly proportional to its absolute temperature.
Nitrogen - forms about 79-80 percent of Earth's atmosphere.
100 - 24.09 = 75.91 75.91%
Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
