(1): Do you expect the mass of 12C and 13C the same? if not, how do we report "average atomic mass" for carbon? what additional information we need to get the average atomic mass for carbon? (1b) If an element has two isotopes, for example 12C, and 13C, list what they have in common and list what they differ.
