Answer : The number of atoms of copper are 
Explanation :
First we have to calculate the moles of copper.

Mass of Cu = 127.08 g
Molar mass of Cu = 63.5 g/mole

Now we have to calculate the number of atoms of copper.
As we know that, 1 mole of substance contains
number of atoms.
As, 1 mole of copper contains
number of copper atoms.
So, 2.00 mole of copper contains
number of copper atoms.
Therefore, the number of atoms of copper are
