Molar and molecular weight of H3GaO3

• Molecular formula: H3GaO3 or Ga(OH)3
• Relative molecular weight of H3GaO3: 120.74502
• Molar mass of H3GaO3: 120.74502 g/mol (0.12075 kg/mol)

Calculation of the relative molecular and molar mass of H3GaO3

• Mr[H3GaO3] = Ar[H] * 3 + Ar[Ga] + Ar[O] * 3 = 1.00794 * 3 + 69.723 + 15.9994 * 3 = 120.74502
• Molar mass (kg/mol) = Mr[H3GaO3] : 1000 = 120.74502 : 1000 = 0.12075 kg/mol

H3GaO3: percent composition by element
