📘 Atom Calculator 

The Atom Calculator helps you calculate the number of atoms in a sample of an element using the mass and molar mass. It applies Avogadro’s number (6.022 × 10²³) to find the atom count from the number of moles.

⚙️ How to Use

  1. Enter the mass of the element in grams.

  2. Enter the molar mass of the element (you can find this on the periodic table).

  3. Click “Calculate Atoms”.

  4. The number of atoms will be displayed below.

🧪 Formula Used

textNumberofatoms=left(fractextmasstextmolarmassright)times6.022times1023\\text{Number of atoms} = \\left( \\frac{\\text{mass}}{\\text{molar mass}} \\right) \\times 6.022 \\times 10^{23}

  • Mass: The weight of the substance in grams.

  • Molar Mass: Grams per mole (g/mol) of the substance.

  • 6.022 × 10²³: Avogadro’s number.
