(28) Fluoxymesterone, C20H29FO3, is an anabolic steroid. A solution is prepared by dissolving 0.01 g of the steroid in 500.0 mL of water. If this solution is diluted to a final volume of 1.00 L. What is the resulting molarity?
(Atomic weights: C = 12.01, O = 16.00, F = 19.00, H = 1.008).
(a) 5.94 x 10-11
(b) 2.38 x 10-11
(c) 5.94 x 10-8
(d) 1.488 x 19-5*
