1. Find the molar mass of KCl:
* Potassium (K) has a molar mass of 39.10 g/mol
* Chlorine (Cl) has a molar mass of 35.45 g/mol
* Molar mass of KCl = 39.10 g/mol + 35.45 g/mol = 74.55 g/mol
2. Use the formula:
* moles = mass / molar mass
3. Plug in the values:
* moles = 48 g / 74.55 g/mol
* moles ≈ 0.644 mol
Therefore, there are approximately 0.644 moles in 48g of KCl.
