Reporting results of concentration of a solution?

Hey so I have a stock solution at 5 mM concentration. I made aliqouts of this solution in water with 1 uL of stock solution in 100uL of water.  I then used 5 uL of the aliquot solution in my experiment. I want to report these results and I think the correct way to do this 5uL of a 1% solution (5 mM with the name of reagent and where is was purchased). Would this be correct. Thank you!

    No, it isn't correct. Why not just calculate and report the actual concentration of the reagent used in the experiment.

    Since you diluted the 5 mM stock 100-fold, its concentration is 50 uM in the solution you actually used. So you could say "5 uL of 50 uM ____ "

      Okay this makes sense. I'm new to solution making so still learning how to make sense of everything, thank you very much!
