There are 3.0 mol of ions in the solution.
Explanation:
HCl is a strong acid. It dissociates completely in solution.
HCl + H₂O → H₃O⁺ + OH⁻
1 mol of HCl produces 1 mol of H₃O⁺ ions and 1 mol of OH⁻ ions, for a total of 2 mol of ions.
So 1.5 mol of HCl produces 1.5 mol of H₃O⁺ ions and 1.5 mol of OH⁻ ions.
This gives us 1.5 mol + 1.5 mol = 3.0 mol of ions.
As a mathematical expression, we would write
