Mole is a unit of numbers just like dozen
As 1 dozen = 12,
1 mole = 6.023 × 10 ²³ (This no. is known as Avogadro's no. or Avogadro's constant)
1 mole of anything ( like bananas, pencils, cars, atoms, etc.) = 6.023 × 10 ²³
No. of moles of molecules of a substance
= No. of molecules / 6.023 × 10 ²³
OR
= weight of substance ( in grams) / molecular weight
