Answer 2

To calculate the molar mass of copper (Cu) and copper chloride (CuCl2), we need to use the periodic table to find the atomic masses of each element involved.

The molar mass of copper (Cu) is approximately 63.55 g/mol.

The molar mass of copper chloride (CuCl2) can be calculated as follows:

Copper (Cu) molar mass: 63.55 g/mol Chlorine (Cl) molar mass: 35.45 g/mol (approximately)

Now, let's calculate the molar mass of copper chloride (CuCl2):

Molar mass of CuCl2 = Molar mass of Cu + 2 * Molar mass of Cl Molar mass of CuCl2 = 63.55 g/mol + 2 * 35.45 g/mol Molar mass of CuCl2 = 63.55 g/mol + 70.9 g/mol Molar mass of CuCl2 = 134.45 g/mol

So, the molar mass of copper chloride (CuCl2) is approximately 134.45 g/mol.
