Hint: Aluminum nitrate ( $Al{\left( {N{O_3}} \right)_3}$ ) is a substance compound which is made up when an aluminum particle joins with a nitrate particle. The particle of aluminum nitrate is shaped by the association of $3$ nitrogen atoms, $1$ aluminum atoms and $9$ oxygen atoms.

Aluminum nitrate is a substance compound which has various uses and is composed of molecules of nitrogen, aluminum, oxygen. Aluminum nitrate has particular substances and actual properties which are utilized for various purposes.
There are $13$ atoms in $Al{\left( {N{O_3}} \right)_3}$
Which is equivalent to stating $AI \times 3{\text{ }}\left( {N{O_3}} \right)$
Which may likewise represent as $N{O_3}{\text{ }} \times 3{\text{ }} = {\text{ }}{N_3}{O_9}$
Along these lines, no of Nitrogen $= {\text{ }}3$ , no of Oxygen $= {\text{ }}9$ , no of Aluminum $= 1$ In $1$ equation unit of $Al{\left( {N{O_3}} \right)_3}$ , there are $9$ atoms of oxygen, $3$ nitrogen atoms, and $1$ aluminum atom.
I have gone on before that the mole ( ${N_A}$ , Avogadro's number) is essentially a lot bigger number, for example ${N_A}{\text{ }} = {\text{ }}6.022 \times 1023$ .
Thus, in $1$ mole of $Al{\left( {N{O_3}} \right)_3}$ there are ( $9 \times {N_A}$ ) $O$ particles.

So, there are $9$ oxygen atoms in $Al{\left( {N{O_3}} \right)_3}$
