Answer:

See explanation

Explanation:

The law of conservation of mass states that mass can neither be created nor destroyed. This implies that in a chemical reaction, we can only have the same number of atoms of each element on both sides of the reaction equation.

If we write 4Fe2S3 it means that we have;

4 * 2 = 8 atoms of Fe

4 * 3 = 12 atoms of S

8 + 12 = 20 atoms in all
