How many moles of ions are there in 3 moles of calcium chloride?

9 moles of ions

Explanation:

Our compound is: CaCl₂ (s)

We dissociate it:

CaCl₂ (aq) → Ca²⁺ (aq) + 2Cl⁻ (aq)

Per 1 mol of chloride, we have 1 mol of calcium cation and 2moles of chlorides, so in total we have 3 moles of ions.

Therefore in 3 moles of chloride, we would have 9 moles of ions (3. 3)
