4. What Is The Molar Mass Of AuCl3?

The molar mass of AuCl3 can be calculated by adding the atomic masses of one gold (Au) atom and three chlorine (Cl) atoms.

The atomic mass of Au is 196.97 g/mol, while the atomic mass of Cl is 35.45 g/mol. Therefore, the molar mass of AuCl3 is:

3(35.45 g/mol) + 1(196.97 g/mol) = 303.33 g/mol

Therefore, the molar mass of AuCl3 is 303.33 g/mol.
