1. Find the molar mass of LiCl:
* Lithium (Li) has a molar mass of 6.941 g/mol.
* Chlorine (Cl) has a molar mass of 35.45 g/mol.
* Molar mass of LiCl = 6.941 g/mol + 35.45 g/mol = 42.391 g/mol
2. Use the formula:
* moles = mass / molar mass
3. Plug in the values:
* moles = 0.550 g / 42.391 g/mol
* moles ≈ 0.0130 mol
Therefore, 0.550 g of LiCl is approximately equal to 0.0130 moles.
