Recall that one mole of any substance contains Avogadro's number of particles (atoms, molecules, ions, etc.).
Avogadro's number is defined as \(6.022 \times 10^{23}\) particles per mole.
Since the problem asks for the number of copper atoms in 1 mole of copper, you simply multiply the number of moles by Avogadro's number.
Set up the calculation as: Number of atoms = (1 mol) \(\times\) \((6.022 \times 10^{23} \text{ atoms/mol})\).
This calculation gives the total number of copper atoms in 1 mole of copper.
