Hi Aish,


 


 


Molar mass of MgCO3 is 84 gms.


therefore 1 mole i.e. 6.023 x 1023 molecules of MgCO3 have a mass of 84 gms.


molecules that will have 8.4 gms mass are: 6.023 x 1023 x 8.4/84 = 6.023 x 1022


Each molecule has : 12(Mg) + 6(C) + [ 3 x 8](O) = 42 protons.


Therefore 6.023 x 1022 molecules will have: 6.023 x 1022 x 42 protons.


 


 


Regards,


Saineel.
