Question

How many grams of sodium chloride (NaCl) are produced when 2.0 moles of sodium (Na) react with excess chlorine gas (Cl\(_2\)? The balanced chemical equation for the reaction is: \[ 2 \, \text{Na} (s) + \text{Cl}_2 (g) \rightarrow 2 \, \text{NaCl} (s) \]

• A. \( 116.9 \, \text{g} \)
• B. \( 58.5 \, \text{g} \)
• C. \( 117.0 \, \text{g} \)
• D. \( 231.5 \, \text{g} \)

Hint:

In stoichiometry, always use the mole ratios from the balanced chemical equation to convert between substances. Don’t forget to calculate the molar mass of compounds to find the mass of the product.
