Why do chemists say a mole is like a dozen eggs?

That never made sense. I don’t get the connection between a word that replaces a number and unit conversions.

I managed to get through HS chemistry without ever really understanding what a mole is and never looked back.

Took it in college, and I have no idea myself.

Avogadro....

One dozen is a collection of 12 smaller units, One mole is a collection of 6.02x10^23 smaller units. Just a way to recognize one being a collection of many. Like these united states.

Because it refers to a specific number of things (6.023 × 10 to the 23rd).
Both a dozen and a mole are a name for an amount of something.

Work with Chem Engineers but we only talk football, and I don’t want to drag science into our conversations. My guess is moles are make believe stuff, like unicorns.

I guess Avagadro got LSU...Burrow with all those moles.

What unit conversion are you even referring to?
Posted on 10/23/19 at 4:57 pm to tuptiger
It's just an easier way to notate a given amount of something. Don't overthink it.

That’s my question
One dozen X 12 eggs/ 1 dozen
I never got how that was entirely related to the mole. I see how it’s related to unit conversions, but not entirely to the mole.
Unit conversions seem separate than the idea of the mole. Maybe the point was and is avagadros number substitutes as unit conversions.
Like time:
1 hour X 60 minutes/ 1 hour
Hours cancel. You’re left with minutes. But the mole is more complex.

Yeah that analogy makes no sense.
My wife took a college chem course for a pre-req, and I discovered a Mole is simply a count of molecules. More useful than weight for measuring chemicals for a reaction.

A mole isn't a unit. It's a number of things.
12 eggs is a dozen eggs.
6.02x10^23 chemistry professors is a mole of chemistry professors.
12 eggs is a dozen eggs.
6.02x10^23 chemistry professors is a mole of chemistry professors.

This is the statement I don’t understand. So, why don’t you say the following is true?
1 dozen eggs X 6.022 times 10^23 eggs/ 1 dozen
6.022 times 10^23 eggs = 1 dozen eggs? 1 dozen eggs = 12 eggs.

Maybe if it was 12 mols it would be more clear.

This is what happens when teachers teach how to do a formula without explaining why.
Kids pass the tests but it's a waste of education once they forget the formula a month later and never actually had any clue why they were doing anything.

Don't tell anyone.
Also, forget eggs and forget conversions.
1 dozen = 12
1 mole = 6.22 x 10^23
That's it.

But there is really no formula.
One mole of an element has 6.02214076×10^²³ atoms. One mole of water has 6.02214076×10^²³ water molecules.
One dozen eggs as 12 eggs.
