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 (mol) = Mass (g) / Molar Mass (g/mol)
3. Plug in the values:
* Moles (mol) = 150 g / 58.44 g/mol
* Moles (mol) ≈ 2.57 mol
Therefore, there are approximately 2.57 moles in 150 grams of NaCl.
