Expert Answer:

One Mole=6.022 ×1023 (Avogadro's No.)   atoms/ions/molecules/particles 

 

No. of moles=Mass /Molecular mass

 

Let us take an example of 2gm of hydrogen.

 

No. of moles of hydrogen molecule=2(wt.)/2(Mol. mass)

 

=1 mole of hydrogen molecules

 

=6.022×1023 molecules of hydrogen.
