question 42

Multiple Choice

Uranium has two isotopes U238 and U235.Enriched uranium,with a greater fraction of U235 required by nuclear reactors,is synthesized by first forming the compound UF6 in the gaseous form and then allowing it to pass through a porous medium.The two isotopes are then separated by diffusion which depends on the rms speeds of the molecules.Given the mass of a fluorine atom is 19 amu,masses of U235 and U238 atoms are 235.043924 amu and 238.050785 amu,respectively,the ratio of the rms speeds of the two uranium hexafluoride molecules is
