How do I calculate moles?

How to find moles?

  1. Measure the weight of your substance.
  2. Use a periodic table to find its atomic or molecular mass.
  3. Divide the weight by the atomic or molecular mass.
  4. Check your results with Omni Calculator.

What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
