ANSWER
Given, Mass of Na = 100g ; Molar mass of Na= 23 g
No. of moles of Na =
23
100
= 4.347
No. of atoms of Na = 4.35 x N
A
(N
A
is the Avagadro's Number)
Given, Mass of Fe = 100g ; Molar mass of Fe= 56 g
No. of moles of Fe =
56
100
= 2.10
No. of atoms of Fe = 2.10 x N
A
(N
A
is the Avagadro's Number)
So, Na has more no. of atoms.
