Expert Answer
Radius of Hydrogen nucleus, RH = Ro A1/3 = Ro
Where A is Mass number
Radius of Fe nucleus RFe = Ro 561/3
Density of hydrogen nuclei , 
= mass / volume = mH / [ (4/3)π RH3 ]
= mass / volume = mH / [ (4/3)π RH3 ]Density of Fe nuclei , 
= mFe / [ (4/3)π RFe3 ]
= mFe / [ (4/3)π RFe3 ]
Density of Fe nucleus and Density of Hydrogen nucleus are same
= = 2.3 × 1017 kg/m3
