Chem Effusion Question (1 Viewer)

[SunnyScience]

"One of the methods of separating Uranium-235 (a nuclear feul) from uranium-238 (non fuel) is by the effusion of their gaseous hexafluorides, (²³⁵UF₆ and ²³⁸UF₆).How much faster will ²³⁵UF₆ effuse than ²³⁸UF₆? Use the following atomic masses (in amu): ²³⁵U: 235.119, ²³⁸U: 238.125, F:18.99840"

This is one of the questions I'm meant to solve before my first Chem1031 tutorial...how on Earth do I do this question?

PLEASE AND THANK YOU.
