1. Find the molar mass of NaCl:
* Sodium (Na) has a molar mass of 22.99 g/mol.
* Chlorine (Cl) has a molar mass of 35.45 g/mol.
* The molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol.
2. Use the formula:
* moles = mass / molar mass
3. Plug in the values:
* moles = 234 g / 58.44 g/mol
* moles ≈ 4.00 mol
Therefore, there are approximately 4.00 moles of NaCl present in 234g.
