Lithium 6 mass
WebExample #5: In a sample of 400 lithium atoms, it is found that 30 atoms are lithium-6 (6.015 g/mol) and 370 atoms are lithium-7 (7.016 g/mol). Calculate the average atomic mass of lithium. Solution: 1) Calculate the percent abundance for each isotope: Li-6: 30/400 = 0.075 Li-7: 370/400 = 0.925. 2) Calculate the average atomic weight: http://www.chem.ualberta.ca/%7Emassspec/atomic_mass_abund.pdf
