Correction: (Find the dot!)
I make it 1 mg/L is 0.3224E-6 iron ions per water molecule.
Incidentally, Avogadro's number goes out of the calculation, all you
needed was the weight ratio (1.0E-6) and the ratio of atomic/molecular
weights (18/55.8 = 0.3226).
This result (0.3226E-6) is the _number_ ratio. We actually _use_
the weight ratio.
