* Identify the elements: Copper (Cu) and Chlorine (Cl)
* Find the atomic masses:
* Copper (Cu): 63.55 g/mol
* Chlorine (Cl): 35.45 g/mol
* Consider the subscripts: There are two chlorine atoms (Cl₂) in the formula.
* Calculate the molar mass:
* (1 x 63.55 g/mol) + (2 x 35.45 g/mol) = 134.45 g/mol
Therefore, the molar mass of copper(II) chloride (CuCl₂) is 134.45 g/mol.
