Review Constants Periodic Table Part A Atomic mass is a weighted average of the masses of the naturally occurring isotopes of that element. For example, consider isotopes of lithium: Abundance Mass Isotope (%) (amu) Li 7.5 6.015 On a mission to a newly discovered planet, an astronaut finds copper abundances of 69.15 % for Cu and 30.85 % for 65Cu. What is the atomic mass of copper for this location? The mass of Cu is 62.9300 amu . The mass...
