Counting Oxygen Atoms in Various Molecular Sets

Step 1 of 4

Here, we are going to calculate the number of oxygen atoms present in each set.

Atom is the smallest tiny representation of an atom.

Chemical formula is the representation of the number of atoms present in the molecule or molecular compound.

(a) four dinitrogen monoxide molecules

The molecular formula of  dinitrogen monoxide is \(\mathrm{N}_{2} \mathrm{O}\)

Thus total number of each atom in the molecule is = \(4 \times\left(\mathrm{N}_{2} \mathrm{O}\right)=\mathrm{N}_{8} \mathrm{O}_{4}\)

Therefore, four dinitrogen monoxide molecules has = four (4) oxygen atoms.
