Explanation:
The given compound is [tex]Fe_{2}O_{3}[/tex] and it contains atoms of iron and oxygen.
Number of atoms of different element present in the given formula are as follows.
Number of iron atoms = 2
Number of oxygen atoms = 3
Thus, total number of atoms present in [tex]Fe_{2}O_{3}[/tex] are as follows.
Total atoms present = number of Fe atoms + number of O atoms
= 2 + 3
= 5
Hence, we can conclude that there are total 5 atoms in a [tex]Fe_{2}O_{3}[/tex].
