Molar and molecular weight of Bi(OH)3

• Molecular formula: Bi(OH)3 or H3BiO3
• Relative molecular weight of Bi(OH)3: 260.00242
• Molar mass of Bi(OH)3: 260.00242 g/mol (0.26 kg/mol)

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

• Mr[Bi(OH)3] = Ar[H] * 3 + Ar[Bi] + Ar[O] * 3 = 1.00794 * 3 + 208.9804 + 15.9994 * 3 = 260.00242
• Molar mass (kg/mol) = Mr[Bi(OH)3] : 1000 = 260.00242 : 1000 = 0.26 kg/mol

Bi(OH)3: percent composition by element
