Answer 1

Two atoms of magnesium

Explanation:

Wikipedia and Boy Scouts

Answer 2

The answer to your question is two atoms of Magnesium

Explanation:

Data

Molecule = MgSO₄

2 molecules of MgSO₄ has

Process

From the options given we know that we must know the number of each element in the molecules of magnesium sulfate.

To determine this number, multiply the coefficient 2 by the subscripts of each element.

2MgSO₄ = Mg₂ S₂ O₈

Conclusion

2 molecules of MgSO₂ have = 2 atoms of Magnesium

2 atoms of Sulfur

8 atoms of Oxygen
