Explanation:

100 grams of magnesium:

1 mole of Mg atom = 6.022×10

23

atoms

This means 24g of Mg has 6.022×10

23

atoms

Then 100 g contains:

Number of Mg atoms=

Molar mass

Given mass

×6.022×10

23

Number of atoms=

24

100

×6.022×10

23

Number of Mg atoms = 2.5×10

24

atoms

100 grams of aluminium:

1 mole of atom= 6.022×10

23

atoms

This means 27g of Al has 6.022×10

23

Then 100 g contains:

Number of Al atoms=

Molar mass

Given mass

×6.022×10

23

Number of Al atoms=

27

100

×6.022×10

23

Number of Al atoms= 2.2×10

24

atoms

Thus, 100g of magnesium has more atoms.
