Which has more nu

Answer :

For sodium


Given: Mass of sodium = 100g


Molar mass of sodium = 23u


Number of atoms = number of moles × 6.022 × 1023




Number of atoms = 4.34 × 6.022 × 1023


Number of atomss = 2.613 × 1024


Thus, 100g of sodium contains 2.613 × 1024 atoms.


For iron


Given: Mass of iron = 100g


Molar mass of iron = 55.8u


Number of atoms = number of moles × 6.022 × 1023




Number of atoms = 1.79× 6.022 × 1023


Number of atoms = 1.07× 1024


Thus, 100g of iron contains 1.07× 1024 atoms.


Therefore, 100g of sodium has more number of atoms.
