When a 45-minute road trip a vehicle emitted 16.7 g of nitrogen dioxide (NO₂) from its exhaust then the mass of nitrogen atoms in this amount of NO₂ would be 5.082 grams.
<h3>What is a Chemical compound?</h3>
The chemical compound is a combination of two or more either similar or dissimilar chemical elements.
for example, H₂O is a chemical compound made up of two oxygen atoms and a single hydrogen atom
The molecular mass of any compound is calculated by the sum of the mass of the individual atom
As given in the problem In a 45-minute road trip a vehicle emitted 16.7 g of nitrogen dioxide (NO₂) from its exhaust
The molecular mass of the NO₂ is the sum of the mass of the nitrogen atom and the oxygen atom.
The mass of the single nitrogen atom is 14, while the mass of the single oxygen atom is 16
the molecular mass of NO₂= mass of the N atom+2×(mass of O atom)
= 14 + 2×16
=46
As 46 grams of NO₂ contain 14 grams of Nitrogen
then 1 gram of NO₂ would contain 14/46 grams of Nitrogen
then 16.7 grams of NO₂ would contain (14/46×16.7) grams of Nitrogen
The mass of a nitrogen atom in 16.7 grams of NO₂ would be 5.082 grams
