Each magnesium chloride (MgCl₂) molecule dissociates into 3 ions in total.

Magnesium chloride (MgCl₂) is a salt which means that, upon dissolving in water, it will dissociate, giving positively charged metal cations (here, magnesium ions) and negatively charged anions formed from nonmetals (here, chloride ions). The balanced reaction equation for magnesium chloride (MgCl₂) dissociation looks like this:

MgCl₂(aq) → Mg²⁺(aq) + 2Cl⁻(aq)

We can see that, upon dissociation, each molecule of magnesium chloride forms a single magnesium ion (Mg²⁺) and two chloride ions (Cl⁻). So, in total, 1 + 2 = 3 ions are formed from each unit of magnesium chloride.
