An Atom Calculator is a simple yet powerful chemistry tool used to calculate the number of atoms present in a given sample of matter. By using basic inputs such as mass and molar mass, the calculator applies Avogadro’s principle to deliver instant, accurate results.

How the Atom Calculator Works  

The Atom Calculator is based on Avogadro’s Law, which states: 1 mole of any substance contains exactly 6.022 × 10²³ atoms 

 🔹 Formula Used Number of Atoms = (Mass ÷ Molar Mass) × Avogadro’s Number 

 Where: Mass = grams of substance 

 Molar Mass = g/mol 

 Avogadro’s Number = 6.022 × 10²³
