Average Atomic Mass Worksheet 2

8) calculate the average atomic mass of lithium, which occurs as two isotopes that have the following atomic masses and abundances in nature: The key difference between atomic mass and average atomic mass is that the atomic mass is the mass of an atom, whereas the average atomic mass is the mass of an atom of a particular chemical element calculated by considering isotopes of that element. The other is mass 7.0160 amu, which accounts for 92.41%.
