Question

which has more number of atom, 100g of sodium or 100g of iron​

Answer 1

Answer:

100g of iron has more atoms

Explanation:

because iron is more stronger and has more mass than sodium

hence it contains more tightly bound atoms.

Answer 2

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.
