Question

how many atoms of oxygen (o) are in the compound: *
2 points
magnesium sulfate
mgso₄
1 atom
3 atoms
4 atoms

Explanation:

Step1: Analyze the chemical formula

The chemical formula of magnesium sulfate is \(MgSO_4\).

Step2: Identify the number of oxygen atoms

In the formula \(MgSO_4\), the sub - script of \(O\) (oxygen) is \(4\). This sub - script indicates the number of oxygen atoms in one formula unit of the compound. So, there are 4 oxygen atoms in \(MgSO_4\).

Answer:

C. 4 atoms
