Identify the chemical formula given: Fe_2O_3, which represents a molecule composed of iron (Fe) and oxygen (O) atoms.
Determine the number of atoms of each element in the molecule: there are 2 iron (Fe) atoms and 3 oxygen (O) atoms.
Add the number of atoms of each element to find the total number of atoms in one molecule: total atoms = number of Fe atoms + number of O atoms.
Write the expression for the total number of atoms: total atoms = 2 + 3.
Calculate the sum to find the total number of atoms in a single molecule of Fe_2O_3.
