What is the formula mass of the iodine molecule?
Answer:
Iodine is a diatomic molecule, and we work out the mass of \(I_{2}\).
Explanation:
The atomic mass of iodine is \(126.9 \cdot g \cdot m o l^{-1}\) (from where did I get that figure?),
and thus its formula mass is \(253.8 \cdot g \cdot m o l^{-1}\).
