Explanation:

Hello!

We know that by the Law of Avogrado, for each mole of substance we have 6.02*10²³ atoms, if:

The molar mass of of magnesium = 24.30 g/mol

If:

1 mol we have 6.02*10²³ atoms

1 mole of Mg we have 24.30 g

Then we have:

24.30 g ------------- 6.02*10²³ atoms

x ----------------------- 7.43*10²² atoms

I Hope this helps, greetings ... DexteR! =)
