There are two important isotopes of uranium- 235 U and 238 U; these isotopes are nearly identical chemically but have different atomic masses. Only 235 U is very useful in nuclear reactors. One of the techniques for separating them (gas diffusion) is based on the different average velocities Vrms of uranium hexafluoride gas. UF6. (a) The molecular masses for 235 U UF6 and 238 U UF6 are 349.0 g/mol and 352.0 g/mol, respectively. What is the ratio of their average velocities?
