C: If the surface area of the Pacific Ocean is 1.6576x10>8 sq. km and the average depth is 4,028 meters, how many moles of water are in the pacific? (Hint: 18cm>3 = 1mole water)
D: If the average penny is 2mm thick, how far toward the sun would a 1 mole stack of pennies reach?

Answer 1

A 'mole' is a chemistry term for 'gram molecular weight' (or 'gram atomic weight') and is equal to an Avogadros number (6.02x10^23) of the things being measured. So a mole of dollars would be 6.02 x 10^23 dollars and, at 10^6 dollars per day, it would take
6.02x10^23 / 10^6 = 6.02x10^17 days (about 1.649x10^15 years. About a hundred thusand times longer than the Universe has existed since the Big Bang ☺)
