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:

x ----------------------- 7.43*10²² atoms
I Hope this helps, greetings ... DexteR! =)
