To find the mass of 1 mole of copper atoms, we need to multiply the mass of one copper atom by Avogadro's number (6.022 x 10^23 atoms/mol).
Mass of 1 mole of copper atoms = (mass of one copper atom) x (Avogadro's number)
= (1.06 x 10^-22 g) x (6.022 x 10^23 atoms/mol)
= 6.38012 x 10^1 g/mol
= 63.8 g/mol
Therefore, the mass of 1 mole of copper atoms is 63.8 g.
A copper atom has a mass of 1.06*10 to power of -22g and a penny has a mass of 2.5g
