**Title:** Calculating the Concentration of MgCl₂ in Solution

A sample of magnesium chloride (MgCl₂) in solid form is added to water. After dissolving, the number of chloride ions present is measured to be \(8 \times 10^{22}\). Your task is to derive an equation to calculate the concentration of MgCl₂, using this value. The concentration refers to the amount of MgCl₂ in the total volume of the solution, which is 5.0 liters. 

**Instructions for Calculation:**

1. Recognize that when MgCl₂ dissolves in water, it dissociates into one magnesium ion (Mg²⁺) and two chloride ions (Cl⁻).
2. Use the measured number of chloride ions to infer the number of MgCl₂ formula units, knowing there are two chloride ions per formula unit.
3. Convert the number of formula units to moles, using Avogadro's number (\(6.022 \times 10^{23}\) formula units/mole).
4. Calculate the molarity (concentration) of the MgCl₂ solution by dividing the moles of MgCl₂ by the total solution volume (5.0 L).

Include each step in the calculation and ensure all units are clearly labeled in your final equation. This method ensures precision and clarity in quantifying the solution's concentration.
