Title: quick dilution problem help needed please
Post by: fluoxymesterone on September 25, 2007, 04:32:27 PM
a standard solution is prepared for the analysis of (C20 H29 F O3). a stock solution is first prepared by dissolving 10.0 mg of the substance in enough water to give a total volume of 500.0 mL. a 100.0 -(ppm parts per million) L 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?
