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
