Avogadro's number is a fundamental constant in chemistry and is defined as:
* 6.02214076 × 1023 entities per mole.
To convert moles to atoms, you multiply the number of moles by Avogadro's number.
Formula:
```
Number of atoms = Number of moles × Avogadro's number
```
Example:
If you have 2 moles of carbon, how many carbon atoms are there?
```
Number of atoms = 2 moles × 6.02214076 × 1023 atoms/mole
= 1.204428152 × 1024 atoms
```
Therefore, there are 1.204428152 × 1024 carbon atoms in 2 moles of carbon.
