Here's how to calculate the molar mass of lithium chloride (LiCl):

* Find the atomic masses:

* Lithium (Li): 6.941 g/mol

* Chlorine (Cl): 35.453 g/mol

* Add the atomic masses together:

* 6.941 g/mol + 35.453 g/mol = 42.394 g/mol

Therefore, the molar mass of lithium chloride (LiCl) is 42.394 g/mol.
