Question

What is the mass of sodium chloride (\( \text{NaCl} \)) formed when 0.5 moles of sodium (\( \text{Na} \)) reacts with excess chlorine (\( \text{Cl}_2 \))?

• A. \( 39 \, \text{g} \)
• B. \( 35.5 \, \text{g} \)
• C. \( 29 \, \text{g} \)
• D. \( 70 \, \text{g} \)

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.
