The nucleus of 6 Li is a powerful absorber of neutrons. It exists in the naturally occurring metal to the extent of 7.5%. In the era of nuclear deterrence, large quantities of lithium were processed to remove 6 Li for use in hydrogen bomb production. The lithium metal remaining after removal of 6 Li was sold on the market. (a) What are the compositions of the nuclei of 6 Li and 7 Li? (b) The atomic masses of 6 Li and 7 Li are 6.015122 and 7.016004 amu, respectively. A sample of lithium depleted in the lighter isotope was found on analysis to contain 1.442% 6 Li. What is the average atomic weight of this sample of the metal?
