1. The problem statement, all variables and given/known data Want to separate two isotopes whose atomic masses differ by one neutron mass. We do this by filling a tube of height H with a gaseous mixture of the two isotopes Derive a formula of the enrichment factor [n1 (H)/ n2 (H)]/ [n1(0)/n2(0)] If the gas from the top of the tube is fed into a second tube, and the processes is repeated N times, how many 10 m long tubes will be needed to make the final concentration .1 from the initial concentration of .001 at room temperature? 2. Relevant equations μ= τ ln [nj/nq] where nq= [mjτ/2∏hbar]^3/2 3. The attempt at a solution Not sure where to even begin with this problem! Any help would be appreciated!!
