Molar and molecular weight of Ga(OH)3

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

Calculation of the relative molecular and molar mass of Ga(OH)3

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

Ga(OH)3: percent composition by element

• Hydrogen (H) = 3.02382 : 120.74502 * 100 = 2.504 %
• Gallium (Ga) = 69.723 : 120.74502 * 100 = 57.744 %
• Oxygen (O) = 47.9982 : 120.74502 * 100 = 39.752 %
