show the relationship between mole,avagadro number and mass

Asked by nilangi | 8th Oct, 2013, 05:16: PM

Expert Answer:

One Mole = 6.022 X 1023 (Avogadro's No.)   atoms/ions/molecules/particles
 
No. of moles = Mass/Molecular weight

No. of atoms = Number of moles ( Given mass / Molar mass ) x Avogadro number

 
Let us take an example of 2gm of hydrogen.
No. Of moles of hydrogen molecule=2(wt.)/2(Mol. wt)  
=1 mole of hydrogen molecules  
=6.022 X 1023  molecules of hydrogen
