How many grams of pure uranium can theoretically be extracted from a 10.0 kg sample of pitchblende, which is 92.0% UO2? Im not looking for the answer. I would just like to know the formula to solve the problem.

  1. Since it's only 92% UO2 then you have only 10 kg x 0.92 = ?kg UO2.
    Convert that many kg UO2 to ? kg U.
    That's ?kg UO2 x (atomic mass U/molar mass UO2) = ? kg of U.
