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. Plug in the values:
* moles = 50 g / 58.5 g/mol
* moles ≈ 0.85 mol
Therefore, 50g of NaCl represents approximately 0.85 moles.
