1.57x10^24 atoms

Explanation:

From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 atoms. From this hypothesis, it means that 1mole of Cu also contains 6.02x10^23 atoms.

1 mole of Cu = 63.5g.

1mole (63.5g) of Cu contains 6.02x10^23 atoms.

Therefore, 165.32g of Cu will contain = (165.32x6.02x10^23) / 63.5) = 1.57x10^24 atoms
