Enriched uranium is produced via gaseous diffusion of UF6. Suppose a process were developed to allow diffusion of gaseous uranium atoms, U (g). Calculate the ratio of diffusion rates of U235 and U238, and compare it to the ratio for UF6 given in the essay.

What essay are you talking about?

The diffusion constant D, which is proportional to the diffusion rate, is proportional to sqrt(1/M), where M is the molecular or atomic weight.

You are probably supposed to compare sqrt(238/235) with sqrt(352/349).

The former applies to the atomic vapor and the latter applies to the hexafluoride.
