What is the mass of sodium chloride (\( \text{NaCl} \)) formed when 0.5 moles of sodium (\( \text{Na} \)) reacts with excess chlorine (\( \text{Cl}_2 \))?
Show Hint
Remember: In a chemical reaction, the number of moles of reactants and products are related by the stoichiometric coefficients in the balanced equation. Use these relationships to convert between moles and mass.
