Enter the number of moles and Avogadro’s number into the calculator to determine the number of particles. This calculator can also evaluate any of the variables given the others are known.

Moles To Particles Formula

The following formula is used to calculate the number of particles from moles.

P = M * A


  • P is the number of particles
  • M is the number of moles
  • A is Avogadro’s number (6.022 x 10^23)

To calculate the number of particles, multiply the number of moles by Avogadro’s number.

What is Moles To Particles?

Moles to particles conversion is a fundamental concept in chemistry used to relate the amount of a substance to the number of constituent particles (atoms, molecules, ions, etc.) in that substance. This is based on Avogadro’s number, which states that one mole of any substance contains 6.022 x 10^23 particles. Therefore, to convert moles to particles, you multiply the number of moles by Avogadro’s number.

How to Calculate Moles To Particles?

The following steps outline how to calculate the number of particles using the formula P = M * A.

  1. First, determine the number of moles (M).
  2. Next, determine Avogadro’s number (A) which is 6.022 x 10^23.
  3. Next, gather the formula from above = P = M * A.
  4. Finally, calculate the number of particles (P).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

number of moles (M) = 2

Avogadro’s number (A) = 6.022 x 10^23
