Atomic mass of sodium = 23u (data)
It means gram atomic mass of sodium = 23 gm
Now atoms present in 23 gm sodium = 6.022 × 1023
= \(\frac{6.022 \times 10^{23}}{23}\times 100\)
It means Number of atoms in 100 gm sodium = 1.6753 × 1024
∴ 100 gm sodium has more number of atoms rather than 100 gms of iron.
