1. Write the Balanced Chemical Equation:
The reaction between sodium (Na) and chlorine (Cl₂) produces sodium chloride (NaCl):
2 Na + Cl₂ → 2 NaCl
2. Determine the Molar Mass of Sodium:
The molar mass of sodium (Na) is approximately 22.99 g/mol.
3. Calculate the Moles of Sodium:
* Moles of Na = (Mass of Na) / (Molar Mass of Na)
* Moles of Na = 92.0 g / 22.99 g/mol
* Moles of Na ≈ 4.00 mol
4. Use the Mole Ratio from the Balanced Equation:
The balanced equation shows that 2 moles of Na react to produce 2 moles of NaCl. This means the mole ratio of Na to NaCl is 1:1.
5. Calculate the Moles of Sodium Chloride:
Since the mole ratio is 1:1, 4.00 moles of Na will produce 4.00 moles of NaCl.
6. Determine the Molar Mass of Sodium Chloride:
The molar mass of sodium chloride (NaCl) is approximately 58.44 g/mol (22.99 g/mol for Na + 35.45 g/mol for Cl).
7. Calculate the Mass of Sodium Chloride:
* Mass of NaCl = (Moles of NaCl) * (Molar Mass of NaCl)
* Mass of NaCl = 4.00 mol * 58.44 g/mol
* Mass of NaCl ≈ 233.76 g
Therefore, approximately 233.76 g of sodium chloride is produced.
