  • We know, mole is a link between the mass of atoms or molecules and the number of atoms or molecules.
  • 1 mole of atoms or molecules = 6.022 × 10^23 atoms or molecules.
  • This number is known as Avogadro Number named after the scientist Amedeo Avogadro.
  • So, the molecular formula of a substance represents 1 mole of molecules of that substance.
  • So, 1 mole of carbon monoxide (CO) contains 6.022 × 10^23.
  • Also, 1 mole of boron trihydride (BH3) contains 6.022 × 10^23.
  • Similarly, 1 mole of water (H20) contains 6.022 × 10^23.

Answer:

6.022 × 10^23
