How many copper atoms are in a penny weighing 3.10 g?

3.10g Cu / 63.55g Cu X 6.022 X 10 ^23 = 2.94 X 10 ^22 Cu atoms.

How many molecules are in a mole?

The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.

How many copper atoms are in 1g of copper?

Since 1 mole of copper weights 63.55 gram. That implies 63.55 gram copper contains one mole of copper that is 63.55gram copper contains 6.023 × 10 ^23 atoms. That implies one gram copper contains (6.023×10^23)/63.55=9.48×10^21 atoms(approximately).
