Molar and molecular weight of AuCl3

• Relative molecular weight of AuCl3: 303.325569
• Molar mass of AuCl3: 303.325569 g/mol (0.30333 kg/mol)

Calculation of the relative molecular and molar mass of AuCl3

• Mr[AuCl3] = Ar[Au] + Ar[Cl] * 3 = 196.966569 + 35.453 * 3 = 303.325569
• Molar mass (kg/mol) = Mr[AuCl3] : 1000 = 303.325569 : 1000 = 0.30333 kg/mol

AuCl3: percent composition by element

• Gold (Au) = 196.966569 : 303.325569 * 100 = 64.936 %
• Chlorine (Cl) = 106.359 : 303.325569 * 100 = 35.064 %
