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 of LiCl = 0.550 g / 42.391 g/mol

* Moles of LiCl ≈ 0.0130 mol

Therefore, 0.550 grams of LiCl is approximately equal to 0.0130 moles.
