1. Dissociation of Sodium Nitrate

Sodium nitrate (NaNO₃) is a strong electrolyte, meaning it completely dissociates into its ions when dissolved in water:

NaNO₃ (aq) → Na⁺ (aq) + NO₃⁻ (aq)

2. Moles of Ions Produced

* For every 1 mole of NaNO₃, you get 1 mole of Na⁺ ions and 1 mole of NO₃⁻ ions.

3. Total Moles of Solute Particles

Therefore, adding one mole of sodium nitrate to water produces 2 moles of solute particles (1 mole of Na⁺ + 1 mole of NO₃⁻).
