Question

How many atoms are in a molecule of iron oxide (Fe2O3)?
A. 3
B. 2
C. 1
D. 5

Answer 1

Iron Oxide Fe2O3 = 5 atoms.

Answer 2

5 atoms are there in a molecule of iron oxide.

Step-by-step explanation:

Number of various atoms in iron oxide =
`Fe_2O_3`

Number of iron atoms = 2

Number of oxygen atoms = 3

Total number of atoms in iron oxide = 2 + 3 = 5

5 atoms are there in a molecule of iron oxide.
