WebThe table shows the mass numbers and abundances of naturally-occurring copper isotopes. Mass number Abundance; 63: 69%: 65: 31%: Calculate the relative atomic mass of copper. WebFeb 4, 2024 · "Average atomic mass = 63.62 amu" "Average atomic mass" is the weighted average of the individual isotopes. And thus the weighted average = (0.6917xx63+0.3083xx65)*"amu" = "?? amu". Note that we have not accounted for the less massive copper isotopes that would decrease this mass to the accepted value of 63.55 …
