Expert Answer
Avogadro's Number:
Avogadro experimentally found that one mole of any substance always contained 6.022 × 1023 particles.
This number is called the Avogadro’s number, denoted by N0.
1 mole of a substance is equal to 6.022 × 1023 particles i.e. atoms, molecules or ions of the substance.
For Example, How many molecules will be present in 2 grams of hydrogen gas (H2)?
1 mole of hydrogen molecules = molecular mass of hydrogen = 2 grams
We know that 1 mole of hydrogen molecules contains 6.022 × 1023 hydrogen molecules.
2 grams of hydrogen gas will also contain 6.022 × 1023 hydrogen molecules.
1 mole (of anything) = 6.022 × 1023 in number
