Answer:

[tex]\boxed {\boxed {\sf 12 \ Mg \ atoms }}[/tex]

Explanation:

We are given this formula:

[tex](Mg_3N_2)_4[/tex]

We want to find the number of magnesium atoms. We can see that there is a subscript of 3 after the magnesium, so there are 3 magnesium atoms in 1 molecule of the compound.

However, there is a subscript of 4 that comes after the entire compound, so there are actually 4 molecules, with each molecule containing 3 magnesium atoms. Multiply 4 and 3.

  • 3 Mg * 4 = 12 Mg

There are 12 magnesium atoms.
