Question

which has greater no. of atoms 100g of sodium or 100g of iron
Atomic mass og no.=2.3u
Fe=56u​

Answer 1

Answer:

sodium has greater no. of atoms because

formula: no. of moles × Avogadro's no.

100/23×6.022×10^23 atoms in nitrogen

no .of atoms in sodium= 2.6177634×10^23 atoms

No. of atoms in Fe 100g =no. of moles × Avogadro's no

=100/56×10^23

1.074927×10^23 atoms

So sodium has more no. of atoms

hope you understand it
