However, ozone present at the surface is a byproduct of smog and thus a pollutant. Another form ( allotrope) of oxygen, ozone ( Oģ), strongly absorbs ultraviolet UVB radiation and the high-altitude ozone layer helps protect the biosphere from ultraviolet radiation.

Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Oxygen is continuously replenished in Earth's atmosphere by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. Most of the mass of living organisms is oxygen as a component of water, the major constituent of lifeforms. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone. The body's circulatory system transports the oxygen to the cells, where cellular respiration takes place.
In tetrapods breathing brings oxygen into the lungs where gas exchange takes place, carbon dioxide diffuses out of the blood, and oxygen diffuses into the blood. Īll plants, animals, and fungi need oxygen for cellular respiration, which extracts energy by the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. Oxygen makes up almost half of the Earth's crust in the form of oxides. Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula OĢ.
Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
Oxygen is the chemical element with the symbol O and atomic number 8. You can also get the formula used in Kilogram Per Mole to Oxygen - Standard Atomic Weight conversion along with a table representing the entire conversion.(O 2) 90.188 K (−182.962 ☌, −297.332 ☏) If you encounter any issues to convert, this tool is the answer that gives you the exact conversion of units. Converting Kilogram Per Mole to Oxygen - Standard Atomic Weight is easy, for you only have to select the units first and the value you want to convert. When you are converting molar mass, you need a Kilogram Per Moles to Oxygen - Standard Atomic Weights converter that is elaborate and still easy to use. helps in the conversion of different units of measurement like kg/mol to O through multiplicative conversion factors. Be it buying grocery or cooking, units play a vital role in our daily life and hence their conversions. Measurement like molar mass finds its use in a number of places right from education to industrial usage. Units of measurement use the International System of Units, better known as SI units, which provide a standard for measuring the physical properties of matter.
