Molar and molecular weight of RuCl3

• Molecular formula: RuCl3 or Cl3Ru
• Relative molecular weight of RuCl3: 207.429
• Molar mass of RuCl3: 207.429 g/mol (0.20743 kg/mol)

Calculation of the relative molecular and molar mass of RuCl3

• Mr[RuCl3] = Ar[Cl] * 3 + Ar[Ru] = 35.453 * 3 + 101.07 = 207.429
• Molar mass (kg/mol) = Mr[RuCl3] : 1000 = 207.429 : 1000 = 0.20743 kg/mol

RuCl3: percent composition by element

• Chlorine (Cl) = 106.359 : 207.429 * 100 = 51.275 %
• Ruthenium (Ru) = 101.07 : 207.429 * 100 = 48.725 %
