Asked by Lyndsay

I did a lab on spectrophotometric determination of iron in vitamin tablets, and I need to calculate the molarity of Fe(o-phenanthroline)3 in each solution and I have no idea how to calculate it. I know the concentration of Fe in the standard solutions in ppm.

And I have no idea what you did. Perhaps we can help if you post how the solutions were prepared.
