Verified step by step guidance1
Identify the chemical formula of the compound, which is NH_3 (ammonia).
Determine the number of atoms of each element in one molecule of NH_3: there is 1 nitrogen (N) atom and 3 hydrogen (H) atoms.
Calculate the total number of atoms in one molecule by adding the atoms of each element: 1 (N) + 3 (H) = 4 atoms.
Since 1 mole of NH_3 contains Avogadro's number of molecules, the total number of moles of atoms in 1 mole of NH_3 is the same as the total number of atoms per molecule, which is 4 moles of atoms.
Express the total moles of atoms as: \$4 \text{ moles of atoms} = 1 \text{ mole NH}_3 \times (1 + 3)$.
