How many grams are in 4.67 moles of NO2? This question delves into the realm of chemistry, where the conversion between moles and grams is a fundamental concept. By understanding the relationship between these units, we can determine the mass of a given substance with precision.
Nitrogen dioxide (NO2) is a compound composed of nitrogen and oxygen atoms, and its molar mass plays a crucial role in this conversion. The molar mass of NO2, expressed in grams per mole (g/mol), is a constant value that allows us to establish the direct relationship between the number of moles and the mass of the substance.
Convert Moles of NO2 to Grams
Converting moles of a substance to grams requires knowledge of its molar mass. Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). The molar mass of NO2 is 46.01 g/mol. The formula for converting moles to grams is:
Mass (grams) = Moles × Molar mass (g/mol)
To calculate the grams of NO2 from 4.67 moles, we can use the formula:
Mass (grams) = 4.67 moles × 46.01 g/mol = 214.67 grams
Chemical Composition of NO2
NO2 is a nitrogen dioxide molecule, composed of one nitrogen atom and two oxygen atoms. It is a reddish-brown gas with a pungent odor. Nitrogen dioxide is a major air pollutant and a precursor to the formation of photochemical smog.
NO2 is produced by the combustion of fossil fuels, such as in vehicles and power plants. It can also be formed through natural processes, such as lightning strikes and forest fires.
Applications of NO2: How Many Grams Are In 4.67 Moles Of No2
NO2 is used in the production of nitric acid, which is a key component in fertilizers and explosives. It is also used as a fuel additive to reduce emissions.
Emerging applications of NO2 include its use in environmental monitoring and medical research. NO2 can be used to detect air pollution and to study the effects of air pollution on human health.
Safety Considerations
NO2 is a toxic gas that can cause respiratory problems, including asthma and bronchitis. Long-term exposure to NO2 can increase the risk of developing cardiovascular disease and cancer.
When handling NO2, it is important to wear appropriate personal protective equipment, such as a respirator and gloves. NO2 should be stored in a well-ventilated area.
Comparison with Other Nitrogen Oxides
NO2 is one of several nitrogen oxides (NOx). Other NOx include NO and N2O.
- NO is a colorless gas that is produced by the combustion of fossil fuels. It is a precursor to the formation of NO2.
- N2O is a colorless gas that is used as an anesthetic and a propellant. It is also a greenhouse gas.
NO2 is more toxic than NO and N2O. It is also a more potent greenhouse gas than N2O.
Common Queries
What is the molar mass of nitrogen dioxide (NO2)?
The molar mass of NO2 is 46.01 g/mol.
How many grams are in 2 moles of NO2?
To calculate the mass, multiply the number of moles (2) by the molar mass (46.01 g/mol): 2 moles – 46.01 g/mol = 92.02 grams.
What is the significance of converting moles to grams?
Converting moles to grams allows us to determine the mass of a substance, which is essential for various chemical calculations and practical applications, such as preparing solutions with specific concentrations or determining the amount of reactants and products in chemical reactions.
