1. Count the Atoms in Each Element:
* Nitrogen (N): There are two nitrogen atoms (one in NH₄ and one in NO₃).
* Hydrogen (H): There are four hydrogen atoms (in NH₄).
* Oxygen (O): There are three oxygen atoms (in NO₃).
2. Total Atoms:
* Add the number of atoms for each element: 2 + 4 + 3 = 9 atoms
Therefore, there are 9 atoms present in one molecule of ammonium nitrate (NH₄NO₃).
