Uranium-235 can be separated from U-238 by fluorinating theuraniumto form UF6 and then taking advantage of thedifferentrates of effusion and diffusion for compounds containingthe twoisotoopes. Calculate the ratio of effusion ratesfor238UF6 and235UF6 .The atomic mass of U-235 is235.054 amu and that of U-238 is 238.051amu.
Gaseous diffusion is used to enrich natural uranium in U-235.Use Grahamâs law (see feedback) to calculate the ratio ofenrichment of U-235 by a single diffusion of UF6. The atomic massesof the two principal isotopes of uranium are 235.0493 and 238.0508for U-235 and U-238, respectively, and that of F is 18.9984
What is an isotope of an element? Explain the difference in thenumber of neutrons and protons in U - 235 and U - 238
