Nitrogen dioxide (NO2) is a chemical compound that is composed of nitrogen and oxygen atoms. It is a brownish-red gas at room temperature and has a strong, pungent smell. NO2 is highly reactive and can be toxic to humans if inhaled in high concentrations.
The molar mass of a chemical compound is the mass of one mole of the compound, expressed in grams per mole. The molar mass of NO2 is 46.006 g/mol. This means that one mole of NO2 weighs 46.006 grams.
NO2 is used in a variety of industrial and scientific applications, including the production of dyes, explosives, and rubber. It is also a byproduct of the burning of fossil fuels and can be formed when nitrogen-containing compounds react with oxygen in the air.
Exposure to high concentrations of NO2 can cause respiratory problems and may exacerbate asthma and other lung conditions. It is classified as a hazardous air pollutant by the Environmental Protection Agency (EPA) in the United States.
