Answer

1 mol of $copper$ has the greater mass.

Work Step by Step

- 1 mol copper: 1 mol copper = $6.022 \times 10^{23}$ copper atoms. Since we are comparing 2 quantities of the same type of atom ($Cu$), the one with the higher number of atoms has the greater mass. $6.022 \times 10^{23} > 1$ Therefore: In mass: 1 mol copper > 1 copper atom.
