1. Balanced Chemical Equation:

The reaction between sodium (Na) and chlorine (Cl₂) produces sodium chloride (NaCl):

2 Na + Cl₂ → 2 NaCl

2. Mole Ratio:

The balanced equation shows that 2 moles of sodium react with 1 mole of chlorine to produce 2 moles of sodium chloride.

3. Calculate Moles of Sodium Chloride:

Since you have 4 moles of sodium, you can use the mole ratio to find the moles of sodium chloride produced:

(4 moles Na) * (2 moles NaCl / 2 moles Na) = 4 moles NaCl

4. Convert Moles to Grams:

To convert moles of sodium chloride to grams, use its molar mass (58.44 g/mol):

(4 moles NaCl) * (58.44 g/mol) = 233.76 g NaCl

Therefore, 233.76 grams of sodium chloride are obtained by the reaction of chlorine with 4 moles of sodium.
