Question

A standard solution is prepared for the analysis of fluoxymesterone (C₂₀H₂₉FO₃), an anabolic steroid. A stock solution is first prepared by dissolving 15.6 mg of fluoxymesterone in enough water to give a total volume of 560.0 mL. A 100.0-μL aliquot (portion) of this solution is diluted to a final volume of 500.0 mL. Calculate the concentration of the final solution in terms of molarity.

Concentration =  M
