What are the respective concentrations (M)of Mg²⁺ and Cl^- afforded by dissolving 0.325 mol MgCl₂in water and diluting to 250 mL? A)0.0013 and 0.0013 B)0.0013 and 0.0026 C)1.30 and.1.30 D)1.30 and 2.60 E)2.60 and 2.60

Question

Quizplus · Accepted Answer

The concentration of Mg²⁺ is 0.325 mol / 0.250 L = 1.30 M. Since MgCl₂ dissociates into one Mg²⁺ and two Cl⁻ ions, the concentration of Cl⁻ is 2 * 1.30 M = 2.60 M.
