🤓 Based on our data, we think this question is relevant for Professor Zysmilich's class at GWU.
During the discussion of gaseous diffusion for enriching uranium, it was claimed that 235UF6 diffuses 0.4% faster than 238UF6. Show the calculation that supports this value. The molar mass of 235UF6 = 235.043930 + 6 × 18.998403 = 349.034348 g/mol, and the molar mass of 238UF6 = 238.050788 + 6 × 18.998403 = 352.041206 g/ mol.
Using the Graham's Law of Effusion, we can calculate the approximate rate of each gases using their molar masses:
