1. Identify the number of N atoms per molecule:

* The chemical formula NH₄OH shows that there is one nitrogen (N) atom in each molecule of ammonium hydroxide.

2. Calculate the number of molecules:

* One mole of any substance contains Avogadro's number of particles (6.022 x 10²³).

* Therefore, 2 moles of NH₄OH contain 2 x 6.022 x 10²³ = 1.2044 x 10²⁴ molecules.

3. Calculate the total number of N atoms:

* Since there's one N atom per molecule, you have 1.2044 x 10²⁴ N atoms in 2 moles of NH₄OH.

Answer: There are 1.2044 x 10²⁴ N atoms in 2 moles of NH₄OH.
