A penny weighs 2.5 grams and is 2.5% copper. Therefore, there is2.5 grams Ã— .025 = .0625 grams of copper in a pennyThen you convert grams to atoms with the molecular weight of copper and Avogadro's constant.0625 grams Ã· 63.5 grams/mol Ã— (6.02 Ã— 1023 atoms) Ã· 12 in one dozen = 4.94 Ã— 1019 dozens of copper atoms

2.84 X 10^23 atoms Cu

12.0 grams copper (1 mole Cu/63.55 grams)(6.022 X 10^23/1 mole Cu) = 1.14 X 10^23 atoms of copper -----------------------------------------

2.15 grams copper (1 mole Cu/63.55 grams)(6.022 X 10^23/1 mole Cu) = 2.04 X 10^22 atoms of copper ------------------------------------------

Copper atoms....an element (copper) is made of many atoms.

The number of atoms in 6.4 grams of copper is 6.07X10^22. Copper has a melting point of 1084.62 degrees Celsius which is equal to 1984.32 degrees Fahrenheit.

The atomic weight of copper is 63.546 grams per mole. 129 kg is equal to 129000 grams. So there are 2030.03 moles of copper. There are 6.022 x 10^23 copper atoms in a mole. So there are 12.22 x 10^26 atoms.
