Explanation In a naturally occurring sample of a given element, it is possible all atoms do not have the same mass. When atoms differ in their mass numbers, these are referred to as isotopes. The atomic mass which is expressed in terms of atomic mass unit (amu) is therefore an average of the mass of the different isotopes that constitute a given element. For example, carbon exists in nature as: Carbon-12: Atomic Mass = 12...
