100g of sodium
mole = 100/23
= 4.34
1 mole = 6.022× 10^23 number of atoms
4.34 mole = ??
= 4.34×6.022× 10^23
= 26.13548×10^23
100g of iron
mole = 100/55.84
= 1.79
1 mole = 6.022× 10^23 number of atoms
1.79 mole = ??
= 1.79× 6.022× 10^23 number of atoms
= 10.77938 × 10^23

Answer:
#answerwithquality
Mass of sodium = Mass of sodium / Molar mass of sodium
= 100/23
= 4.34
(ii) Moles of iron = Mass of iron / Molar mass of iron
= 100/56
= 1.78
We find that 100 grams of sodium contain 4.34 moles of atom whereas 100 grams of iron contain 1.78 moles of atoms. Since 100 grams of sodium has more moles, it contains more atoms than 100 grams of iron.
