1.

1 doz = 12
1 penny = 3.00x1022 copper atoms

1 penny×3.00×1022 copper atoms1 penny×1 dozen12 copper atoms = 2.5x1021 dozens


There are 2.5x1021 dozens of copper atoms in a penny.

1 gross = 144
1 penny = 3.00x1022 copper atoms

1 penny×3.00×1022 copper atoms1 penny×1 gross144 copper atoms = 2.08x1020 gross


There are 2.08x1020 gross of copper atoms in a penny.
