Molar and molecular weight of O2Ru

• Molecular formula: O2Ru or RuO2
• Relative molecular weight of O2Ru: 133.0688
• Molar mass of O2Ru: 133.0688 g/mol (0.13307 kg/mol)

Calculation of the relative molecular and molar mass of O2Ru

• Mr[O2Ru] = Ar[O] * 2 + Ar[Ru] = 15.9994 * 2 + 101.07 = 133.0688
• Molar mass (kg/mol) = Mr[O2Ru] : 1000 = 133.0688 : 1000 = 0.13307 kg/mol

O2Ru: percent composition by element

• Oxygen (O) = 31.9988 : 133.0688 * 100 = 24.047 %
• Ruthenium (Ru) = 101.07 : 133.0688 * 100 = 75.953 %
