1. Atoms per molecule:
* Ammonia (NH₃) has 1 nitrogen atom (N) and 3 hydrogen atoms (H) for a total of 4 atoms per molecule.
2. Avogadro's Number:
* One mole of any substance contains 6.022 x 10²³ particles (atoms, molecules, etc.). This is known as Avogadro's number.
3. Calculation:
* Atoms in 1 mole of ammonia: (4 atoms/molecule) x (6.022 x 10²³ molecules/mole) = 2.409 x 10²⁴ atoms
Therefore, there are 2.409 x 10²⁴ atoms in 1 mole of ammonia.
