Copper atoms are heavier than magnesium atoms. So, although each atom of magnesium can produce one atom of copper, the masses won’t be the same. The ratio of the atomic weight of copper to the atomic weight of magnesium is about 2.61. Given this ratio and the initial mass of the magnesium strip (0.38 g) measured in task 1, part A, calculate the mass of copper that can be produced. Recall: Mg + Cu(NO3)2 → Cu + Mg(NO3)2
