Verified step by step guidance1
Identify the chemical formula given: NH_3, which represents ammonia.
Determine the number of each type of atom in one formula unit: N (nitrogen) has 1 atom, and H (hydrogen) has 3 atoms.
Add the number of atoms of each element to find the total number of atoms in one formula unit.
Write the expression for the total number of atoms as: \$1 \text{ (N)} + 3 \text{ (H)}$.
Sum the values to get the total number of atoms present in one formula unit of NH_3.
