Which will make you more wealthy, one mole of pennies (6.02e23 pennies) or one mole of gold atoms (6.02e23 atoms)?
1 mol pennies will be 6.02E23 x $0.01/penny = 6.0E21 dollars which is a huge number.
1 mol Au atoms will be about 197 g. I don't know the price of gold but you can look it up and multiply price/gram x 197 g to get that. I'd rather have a mole o pennies.
