100 g of sodium:
Number of sodium atoms
=given mass/molar mass × 6.022×10^23
=100/23× 6.022×10^23
= 2.62 x 1024 atoms.
100 g of iron :
Number of iron atoms
=given mass/molar mass/6.022×10^23
= 100/56× 6.022×10^23
= 1.07 x 1024 atoms
Thus, 100 g of sodium has more atoms.

Answer: No. of atoms in Sodium (Na) = 4.34
No. of atoms in Iron (Fe) = 1.78
Explanation:
No. of atoms in 100 grams Sodium = 100/23
= 4.34
No. of atoms in 100 grams Iron = 100/56
= 1.78
Therefore, Sodium has more number of atoms.
