A standard solution is prepared for the analysis of fluoxymesterone (C20H29FO3), an anabolic steroid. A stock solution is first prepared by dissolving 13.4 mg of fluoxymesterone in enough water to give a total volume of 500.0 mL. A 100.0-┬ÁL aliquot (portion) of this solution is diluted to a final volume of 100.0 mL. Calculate the concentration of the final solution in terms of molarity.

  • chemistry -

    mols = grams/molar mass
    M = mols/L soln = mols/0.5L = ?
    Call that M
    Then the dilution step is
    M x (1E-3 mL/100 mL) = ?
