Given
Atomic mass of Na = 23 u
Atomic mass of Fe = 56 u
Then, gram atomic mass of Na = 23 g
Now, 23 g of Na contains = 6.022 x 1023 g number of atoms
Thus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms)
100 g of Na contains = 2.6182 x 1024 number of atoms
Then, gram atomic mass of Fe = 56 g
Now, 56 g of Fe contains = 6.022 x 1023 g number of atoms
Thus, 100 g of Fe contains = 6.022 x 1023 / (56 x 100 number of atoms)
100 g of Fe contains = 1.0753 x 1024 number of atoms
Therefore, 100 grams of sodium contains more number of atoms than 100 grams of iron.
