1. Find the molar mass of NaCl:
* Sodium (Na) has a molar mass of approximately 23 g/mol.
* Chlorine (Cl) has a molar mass of approximately 35.5 g/mol.
* The molar mass of NaCl is 23 g/mol + 35.5 g/mol = 58.5 g/mol
2. Use the formula:
* Moles = Mass / Molar Mass
3. Calculate:
* Moles = 8 g / 58.5 g/mol
* Moles ≈ 0.137 mol
Therefore, there are approximately 0.137 moles in 8 grams of NaCl.
