Chemistry Concentration Help?

Question

A purple solution is 16.05 mg/L in sodium salicylate, 0.15 M in HCL and 0.065 M in iron(III) ions. What are the concentrations of these three once you diluted the 10.00 ml to a final volume of 50.00 ml in volumetric flask?

This has me really confused, any help would be appreciated

Answer 1

Each one is a fifth of what it was before dilution.
You can have several solutes in the same solution, each with its own molarity.
