1. Identify the Ions:

* Calcium hydroxide (Ca(OH)₂) dissociates into one calcium ion (Ca²⁺) and two hydroxide ions (OH⁻).

2. Determine the Total Number of Moles of Ions:

* For every 1 mole of Ca(OH)₂:

* You get 1 mole of Ca²⁺ ions.

* You get 2 moles of OH⁻ ions.

* This means a total of 1 + 2 = 3 moles of ions.

3. Calculate for the Given Amount:

* You have 2 moles of Ca(OH)₂.

* Since there are 3 moles of ions per mole of Ca(OH)₂, you have a total of 2 * 3 = 6 moles of ions.

Therefore, there are 6 moles of ions in 2 moles of Ca(OH)₂.
