I want to know the answer to the following question:
How does the weight of uranium-238 compare to that of uranium-235?
All the background I'm provided with is that "In this process, uranium hexafluoride is repeatedly diffused through a silver-zinc membrane, and the different isotopes of uranium are separated by diffusion rate (since uranium 238 is heavier it diffuses slightly slower than uranium-235).". Is that enough to answer the question?
