How many atoms of nitrogen are in a molecule of Al(No3)3

To determine the number of atoms of nitrogen in a molecule of Al(NO3)3, we need to examine the chemical formula and count the number of nitrogen atoms.

In Al(NO3)3:
- "Al" represents the element aluminum.
- "(NO3)3" refers to three nitrate ions.

The nitrate ion (NO3-) consists of one nitrogen atom and three oxygen atoms. Since there are three nitrate ions in the formula, there are three nitrogen atoms in total.

Therefore, there are 3 nitrogen atoms in a molecule of Al(NO3)3.
