Molar and molecular weight of Ga2O3

• Relative molecular weight of Ga2O3: 187.4442
• Molar mass of Ga2O3: 187.4442 g/mol (0.18744 kg/mol)

Calculation of the relative molecular and molar mass of Ga2O3

• Mr[Ga2O3] = Ar[Ga] * 2 + Ar[O] * 3 = 69.723 * 2 + 15.9994 * 3 = 187.4442
• Molar mass (kg/mol) = Mr[Ga2O3] : 1000 = 187.4442 : 1000 = 0.18744 kg/mol

Ga2O3: percent composition by element
