Molar and molecular weight of GeO2

• Relative molecular weight of GeO2: 104.6388
• Molar mass of GeO2: 104.6388 g/mol (0.10464 kg/mol)

Calculation of the relative molecular and molar mass of GeO2

• Mr[GeO2] = Ar[Ge] + Ar[O] * 2 = 72.64 + 15.9994 * 2 = 104.6388
• Molar mass (kg/mol) = Mr[GeO2] : 1000 = 104.6388 : 1000 = 0.10464 kg/mol

GeO2: percent composition by element

• Germanium (Ge) = 72.64 : 104.6388 * 100 = 69.42 %
• Oxygen (O) = 31.9988 : 104.6388 * 100 = 30.58 %
