Chemistry: Molecular Iodine and Atomic Iodine

[Ly444999]

So I just had a question about calculating moles atomic iodine when you have the moles of molecular iodine. In the chemical equation IO₃^-(aq) + I^-(aq) + H⁺(aq) = I₂(aq) + H₂O(l)

Would the moles of atomic iodine be equal to the moles of the molecular iodine? or would the moles of atomic iodine be twice as much as molecular iodine?

Edit: Just realized the equation is unbalanced:
IO₃^-(aq) + 5I^-(aq) + 6H⁺(aq) = 3I₂(aq) + 3H₂O(l)

What about

I₂ → 2I

Does it answer your question?
