How is a mole similar to a dozen?
A mole is similar to a dozen, because both are words used to describe a specific number of countable things.
For example,
"Dozen", "score", and "mole" are words that describe a specific number of objects. Avogadro did not invent the mole, but the number of particles in a mole is called Avogadro's number in his honour. This amazing video by Tyler DeWitt gives an introduction to moles:

A mole is similar to a dozen in that both represent quantities. A mole represents 6.022 x 10^23 entities (atoms, molecules, ions, etc.), while a dozen represents 12 entities. They are both used as units of measurement to quantify large numbers of items.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
