Explain when a mixture of 235UF6 and 238UF6 isotopes is allowable to effuse through a small orifice between two chambers the chamber on the low-pressure side is slightly enriched in the lighter isotope. Starting with the natural abundance of isotopes (0.72% 235U and 99.28% 238U), Explain how many successive stages of enrichment are required to obtain gas that consists of 21% 235UF6?Enter the correct numerical val
