Answer : Average atomic weight of copper atoms will be 63.62 u.
Explanation : For calculating average atomic weight for any given atom we use this formula,
m = Σ
X % abundance
where, m - avg atomic mass of isotope.
and - mass of isotope
on solving we get,
m = [63 u X (69/100)] + [65 u X (31/100)] = 63.62 u.
