Answer:

Mg⁺² = 0.525 mol/L

Cl⁻ = 1.05 mol/L

Explanation:

The formula for magnesium chloride is MgCl₂, and in a solution the following process takes place:

  • MgCl₂ → Mg⁺² + 2Cl⁻

By analyzing the stoichiometric coefficients, we can tell that the concentration of Mg⁺² ions is the same as the concentration of MgCl₂, while the Cl⁻ concentration is twice that value.

In other words:

  • Mg⁺² concentration = MgCl₂ concentration = 0.525 mol/L
  • Cl⁻concentration = 2 * MgCl₂ concentration = 1.05 mol/L
