How many particles are in one mole of a substance?

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.

How do you find the number of particles in a mole?

Calculating the number of particles

  1. The number of particles in a substance can be calculated using:
  2. Number of particles = Avogadro constant × the amount of substance in mol.
  3. Calculate the number of water molecules in 0.5 mol of water.
  4. Number of water molecules = Avogadro constant x amount of substance in mol.
