Free online atoms to moles calculator. Quickly and accurately calculate the number of moles in a given number of atoms.
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.
Solved Example
Example:- let’s say you have 2.5 × 10^24 atoms of a substance. To convert into the number of moles.
solve, use this formula and put the value
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
