Approximately 0.113 grams of sodium chloride is produced when 0.29 grams of sodium iodide reacts with chlorine gas. This was calculated using stoichiometric principles based on the balanced chemical reaction. By determining the moles of sodium iodide and applying the mole ratio, we converted the result back to grams.
