Identify the chemical formula of the molecule given, which is HNO3.
Break down the formula into its constituent atoms: H (hydrogen), N (nitrogen), and O (oxygen).
Count the number of each type of atom in the molecule: 1 hydrogen atom, 1 nitrogen atom, and 3 oxygen atoms.
Add the number of atoms together to find the total number of atoms in one molecule: 1 (H) + 1 (N) + 3 (O).
Sum these values to get the total number of atoms present in one molecule of HNO3.
