A lot! 154 kg copper (1000 grams/1 kg)(1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 1.46 X 1027 atoms of copper ---------------------------------------

Copper is an element it has only one type of atom
1.20x10^24 atoms x 1 mole/6.02x10^23 atoms = 1.99 moles
Copper is an element. You can have a single atom or many atoms and it's still copper.
The atomic weight of copper is 63.546 grams per mole. 129 kg is equal to 129000 grams. So there are 2030.03 moles of copper. There are 6.022 x 10^23 copper atoms in a mole. So there are 12.22 x 10^26 atoms.
The answer is 47,128 x 1023 atoms.
4.682x10^24
214 sheets of copper
Copper is normally encountered as metal which is a giant lattice of atoms.
