Maybe you should review molar mass...

To determine the mass of 1 mole of BaCl3 (barium chloride), you need to know the molar mass of BaCl3. The molar mass is the sum of the atomic masses of all the atoms in a molecule.

The atomic masses of the elements comprising BaCl3 are as follows:
- Barium (Ba): 137.33 g/mol
- Chlorine (Cl): 35.45 g/mol

Since there are three chlorine atoms in one molecule of BaCl3, you need to multiply the atomic mass of chlorine by 3.

Calculating the molar mass:
Molar mass of BaCl3 = (1 x molar mass of barium) + (3 x molar mass of chlorine)
= (1 x 137.33 g/mol) + (3 x 35.45 g/mol)
= 137.33 g/mol + 106.35 g/mol
= 243.68 g/mol

Therefore, the molar mass of BaCl3 is 243.68 g/mol.

Now, if you have 1 mole of BaCl3, you can simply multiply the molar mass by the number of moles to calculate the mass:

Mass of 1 mole of BaCl3 = molar mass of BaCl3
= 243.68 g/mol

So, 1 mole of BaCl3 has a mass of 243.68 grams.
