Question

How many atoms are in one dozen? How many atoms are in 1 mole?

Answer 1

There are exactly `6.022 times 10^23` atoms in 1 mole of any substance. I assume that a dozen atoms is 12 atoms. If you mean a dozen moles it is `12(6.022 times 10^23)` atoms

Explanation:

`6.022 times 10^23` is known as Avogadro's Number and is the number of molecules in 1 mole of a substance.

Answer 2

`"Well, there are 12 atoms in one dozen atoms...."`

`"and 13 atoms in a Bakers' dozen atoms..."`

Explanation:

And if we got a `"mole of atoms"`, `"a chemist's dozen"`, there are `6.022xx10^23` individual atoms...
