Convert Grams to Atoms

Convert Grams to Atoms

How to use Grams to Atoms calculator?

You can use this calculator to know the no. of atoms in certain grams of an element when the atomic mass is provided. 

Just enter the Atomic mass of an element and Grams and you will get how many atoms are there in the entered gram(s).

How to convert Grams to Atoms?

To convert grams to atoms, we need to use the formula below:

Atoms = (grams * Avogadro’s number) / Atomic Mass

Where Avogadro’s number (N) is the number of atoms in one mole of a substance and is approximately 6.02214076 * 10^23 atoms per mole.

Here is the step-by-step process to convert grams to atoms:

  1. Determine the atomic mass of the element you want to convert to atoms. This value is usually expressed in grams per mole (g/mol) and can be found in the periodic table.
  2. Determine the number of grams you have. This is the value that you want to convert to atoms.
  3. Multiply the number of grams by Avogadro’s number:

    grams * N = atoms

  4. Divide the result from step 3 by the atomic mass:

    atoms = (grams * N) / Atomic Mass

  5. The final result is the number of atoms in the given number of grams.


This formula is useful in many fields, including chemistry, materials science, and physics. By converting grams to atoms, you can study the properties and behaviors of substances at the atomic level and better understand the fundamental nature of matter.
