Molar and molecular weight of IrCl3

• Molecular formula: IrCl3 or Cl3Ir
• Relative molecular weight of IrCl3: 298.576
• Molar mass of IrCl3: 298.576 g/mol (0.29858 kg/mol)

Calculation of the relative molecular and molar mass of IrCl3

• Mr[IrCl3] = Ar[Cl] * 3 + Ar[Ir] = 35.453 * 3 + 192.217 = 298.576
• Molar mass (kg/mol) = Mr[IrCl3] : 1000 = 298.576 : 1000 = 0.29858 kg/mol

IrCl3: percent composition by element

• Chlorine (Cl) = 106.359 : 298.576 * 100 = 35.622 %
• Iridium (Ir) = 192.217 : 298.576 * 100 = 64.378 %
