What Is The Molar Mass Of Gold III Chloride?

The molar mass of gold III chloride, also known as auric chloride, is the sum of the atomic masses of all the atoms in one mole of the compound.

To calculate this, we first need to determine the chemical formula for gold III chloride. The Roman numeral III indicates that gold has a +3 oxidation state, while chloride is a monatomic anion with a -1 charge.

Using these pieces of information, we can write the chemical formula as AuCl3.

Next, we look up the atomic masses of gold and chlorine from the periodic table, which are 196.97 g/mol and 35.45 g/mol, respectively.

Finally, we add the products of each atomic mass multiplied by the number of atoms in the formula unit:

Molar mass of AuCl3 = (1 x 196.97 g/mol) + (3 x 35.45 g/mol) = 303.32 g/mol

Therefore, the molar mass of gold III chloride is approximately 303.32 g/mol.
