Answer:
303.32557 g/mol.
Explanation:
Gold III Chloride is also known as acid gold trichloride.
PROPERTIES OF GOLD III CHLORIDE,AuCl3:
Gold III Chloride exist in colour appearance of Red crystals,and yellow crystals. It has a melting point of 254 °C and a density of
4.7 g/cm3. AuCl3 exist as a dimer( Au2Cl6) and it is somewhat covalent.
Molar mass is the the mass of one mole of a substance and is expressed in g/mol. Gold atomic mass is 196.96657, chlorine has 35.453.
Hence, molar mass of AuCl3= atomic number of Gold + atomic mass of chlorine × (number of atoms of chlorine in AuCl3).
Molar mass of AuCl3 = 196.96657 + (35.453 × 3). = 196.96657 + 106.359.
Molar mass of AuCl3= 303.32557 g/mol.
