Solution:
Step 1: Write and balance the chemical equation.
2NaCl → 2Na + Cl₂
Step 2: Calculate the molar mass of substances needed.
For Na
molar mass = 22.99 g/mol × 1
molar mass = 22.99 g/mol
For Cl₂
molar mass = 35.45 g/mol × 2
molar mass = 70.90 g/mol
Step 3: Determine the mole ratios needed.
For Na
mole ratio = 2 mol NaCl : 2 mol Na
For Cl₂
mole ratio = 2 mol NaCl : 1 mol Cl₂
Step 4: Calculate the masses of Na and Cl₂ produced using their respective mole ratios.
For Na
[tex]\text{mass of Na = 4.80 mol NaCl} × \frac{\text{2 mol Na}}{\text{2 mol NaCl}} × \frac{\text{22.99 g Na}}{\text{1 mol Na}}[/tex]
[tex]\boxed{\text{mass of Na = 110.4 g}}[/tex]
For Cl₂
[tex]\text{mass of Cl₂ = 4.80 mol NaCl} × \frac{\text{1 mol Cl₂}}{\text{2 mol NaCl}} × \frac{\text{70.90 g Cl₂}}{\text{1 mol Cl₂}}[/tex]
[tex]\boxed{\text{mass of Cl₂ = 170.2 g}}[/tex]
