1. The Chemical Formula

Barium acetate has the chemical formula Ba(C₂H₃O₂)₂. This tells us that one molecule of barium acetate contains:

* One barium cation (Ba²⁺)

* Two acetate anions (C₂H₃O₂⁻)

2. Ions per Molecule

Therefore, each molecule of barium acetate dissolved in water will produce a total of 1 + 2 = 3 ions.

3. Total Ions from Four Molecules

Since we have four molecules of barium acetate, the total number of ions produced would be 4 molecules * 3 ions/molecule = 12 ions.
