Mole Problems

A mole is a unit for a number of atoms (like you have a dozen eggs, you have a mole of atoms). There are 6.02 x 10^23 atoms in a mole (Avogadro's number), which is where the imaginary phone number came from. A mole is also a small rodent that digs tunnels and causes problems in lawns (a reason you would need to call someone about moles).
