1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
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 ------------------------------------------
