Calculate the molar mass of CuCl_(2) Your answer

To calculate the molar mass of \( CuCl_2 \), we need to sum the molar masses of each atom in the compound:<br /><br />1. Copper (Cu): The atomic mass of copper is approximately 63.55 g/mol.<br />2. Chlorine (Cl): The atomic mass of chlorine is approximately 35.45 g/mol.<br /><br />Since \( CuCl_2 \) contains one copper atom and two chlorine atoms, the calculation is as follows:<br /><br />\[ \text{Molar mass of } CuCl_2 = (1 \times 63.55 \, \text{g/mol}) + (2 \times 35.45 \, \text{g/mol}) \]<br /><br />\[ \text{Molar mass of } CuCl_2 = 63.55 \, \text{g/mol} + 70.90 \, \text{g/mol} \]<br /><br />\[ \text{Molar mass of } CuCl_2 = 134.45 \, \text{g/mol} \]<br /><br />Therefore, the molar mass of \( CuCl_2 \) is 134.45 g/mol.
