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
* Molar mass of NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol
2. Use the formula:
* moles = mass / molar mass
3. Plug in the values:
* moles = 5 g / 58.44 g/mol
* moles ≈ 0.085 mol
Therefore, there are approximately 0.085 moles in 5 grams of NaCl.
