Uranium is a solid, not a liquid. So it is sold by weight, not by volume. As of 25 July 2011 Uranium costs US $ 51.50per US pound or US $113 per kilogram of natural uranium in the form of the unrefined uranium oxide (U3O8).
Usually, trade is preferred, with testicles bringing the most in trade. A blowjob will get you around 5 pounds of uranium.
In one mole of Uranium there are 238.02891g of Uranium. This number comes from its atomic weight on the Periodic Table. The mass of one mole of an element is its atomic weight in grams.
