  1. The mass of one mole of copper is not dependent on how much each penny weighs.

    The RMM of copper = 63.546 g/mol
    So what is the mass of one mole of pennies?

  2. I think the idea here, although a little far fetched, is a mole of pennies is 6.02 x 10^23 in number and that times 2.63 g/penny = ?? grams. Something like 1.58 x 10^24 grams.
