Hydrogen makes up about 11% of the Earth's hydrosphere.
The mass percent of oxygen is approximately 21% in Earth's atmosphere.
The percent of oxygen in dry air is approximately 21%.
Oxygen makes up 21 percent of the air by volume.
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
According to Education.com, the hydrosphere is made of oxygen at 86 percent, hydrogen at 11 percent and other elements totalling 3 percent.
About 30 Percent of the earth is not the hydrosphere
Hydrogen makes up about 11% of the Earth's hydrosphere.
The hydrosphere covers approximately 71% of the Earth's surface.
Troposphere: nitrogen Lithosphere and hydrosphere: oxygen
The elements that are in Earths Hydrosphere is Oxygen with 33.0% of volume, Hydrogen with 66.0% of volume, and 1.0% of unknown elements.
The most abundant element found in the hydrosphere is oxygen. It is mainly present in water molecules (H2O) and dissolved oxygen.
Hydrosphere is made up of water, salt and others so that why i'm giving you this.....(remember water is made up of oxygen and hydrogen,common salt is made up of sodium and chlorine)
Approximately 71% of the Earth's surface is covered by the hydrosphere, which includes all the water on and below the Earth's surface.
The hydrosphere is made up of a variety of gases including oxygen, hydrogen, and carbon dioxide. The hydrosphere includes water in several forms including in gaseous states.
97 % salt, 3 % fresh.
The Earth's troposphere, hydrosphere, and lithosphere contain relatively large amounts of oxygen. In the troposphere, oxygen is a major component of the atmosphere, while in the hydrosphere, it is essential for the formation of water (H2O). Additionally, oxygen is a key element in various minerals and rocks found in the lithosphere.
