How many moles are in copper?

Solution: The mass of 1 mole (6.022 x 1023 atoms) of copper is 63.55 g. The sample we are considering has a mass of 3.14 g. Since the mass is less than 63.55 g, this sample contains less than 1 mole of copper atoms.

Which weighs more a mole of copper or a mole of gold?

Answer: Because 1 mole is a fixed quantity of particles (6.022 × 1023 ), 1 mole of copper contains the same number of atoms as 1 mole of gold. Answer: Because each copper atom has less mass than each gold atom, 1 gram of copper contains more atoms than 1 gram of gold.

How many moles of copper atoms are in a penny?
