Verified Answer :

since you have 3 atoms of sulfur in that molecule in on mole of it you would have 3 moles of sulfur

Answer: There are 3 moles of sulfur atoms present in 1 mole of \(Fe_2(SO_4)_3\)

Explanation:

In the given compound \(Fe_2(SO_4)_3\), there are 3 elements present: iron, sulfur and oxygen.

There are 2 moles of iron element, 3 moles of sulfur element and 12 moles of oxygen element present in 1 mole of \(Fe_2(SO_4)_3\)

Hence, there are 3 moles of sulfur atoms present in 1 mole of \(Fe_2(SO_4)_3\)
