Question

which has more number if atoms 100g of sodium or 100g of iron

Answer 1

since molar mass of sodium is less than the molar mass of iron , therefore there will be more moles of sodium in100gm amount. since sodium has more moles therefore it has more number.

Answer 2

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.
