5. What is the molar mass of AuCl3?
use a periodic table to find the mass of Au and Cl (the Cl mass would be x3)
then u add them...simple
Here is a site that will calculate it for you.

To find the molar mass of AuCl3 (gold chloride), you need to know the atomic masses of the elements involved: gold (Au) and chlorine (Cl).
1. Look up the atomic mass of gold (Au) from the periodic table. It is approximately 196.97 grams per mole (g/mol).
2. Look up the atomic mass of chlorine (Cl) from the periodic table. It is approximately 35.45 g/mol.
3. Identify the number of each element in the chemical formula. In AuCl3, there is 1 gold atom (Au) and 3 chlorine atoms (Cl).
4. Multiply the atomic mass of each element by the number of atoms in the formula. For gold (Au), multiply 196.97 g/mol by 1, which gives you 196.97 g/mol. For chlorine (Cl), multiply 35.45 g/mol by 3, which gives you 106.35 g/mol.
5. Add up the individual masses to get the molar mass of AuCl3. In this case, 196.97 g/mol (from gold) + 106.35 g/mol (from chlorine) equals 303.32 g/mol.
Therefore, the molar mass of AuCl3 is approximately 303.32 g/mol.
