How to convert atoms to moles?
To convert the number of moles from the number of atoms, you need to use Avogadro’s number, which is approximately 6.022 × 10^23 atoms/mol.
1. Determine the number of atoms you have.
2. Divide the number of atoms by Avogadro’s number to convert to moles.
Atoms to moles formula
NM = NA / AN
- NM = Number of moles
- NA = Number of atoms
- AN = Avogadros number = 6.022 × 10^23 atoms/mol
- Number of moles = Number of atoms / 6.022 × 10^23 atoms/mol.
How to calculate atoms to moles?
Example:- let’s say you have 2.5 × 10^24 atoms of a substance. To convert into the number of moles.
NM = NA / AN
Number of moles = Number of atoms/ 6.022 × 10^23 atoms/mol
Number of moles = 2.5 × 10^24 atoms / 6.022 × 10^23 atoms/mol = 4.15 mol
2.5 × 10^24 atoms of substance is equal to 4.15 moles

FAQ
how many moles are equivalent to 5.75×1024 atoms of al?
1 mole of any substance contains 6.022×10^23 atoms since
1 mole of Al = 6.022×10^23 atoms (Avogadro’s number)
Now, let’s calculate the number of moles for 5.75×10^24 atoms of Al:
Number of moles = (5.75×10^24 atoms) / (6.022×10^23 atoms/mole) = 9.55 mol
Therefore, 5.75×10^24 atoms of Al is equivalent to approximately 9.55 moles of Al.
