I think what the commenter is referring to is why use Avogadro's number instead of say, just Sextillions or Septillions.

- XorNot 8y agoI mean that really comes back to the "practical units" thing (and that chemists were the ones doing the work) - a kilogram of anything in chemistry is a huge amount, whereas a gram is about right to make "a lot" of something (in synthesis research people get excited about gram-scale synthetic yields). So it's pretty much chosen to get integer-ish units with common things you work with like carbon - i.e. 1 mole of carbon of is ~12 grams.
- aylmao 8y agoYeah, that makes sense (:
