Molar and molecular weight of KBO2

• Molecular formula: KBO2 or BKO2
• Relative molecular weight of KBO2: 81.9081
• Molar mass of KBO2: 81.9081 g/mol (0.08191 kg/mol)

Calculation of the relative molecular and molar mass of KBO2

• Mr[KBO2] = Ar[B] + Ar[K] + Ar[O] * 2 = 10.811 + 39.0983 + 15.9994 * 2 = 81.9081
• Molar mass (kg/mol) = Mr[KBO2] : 1000 = 81.9081 : 1000 = 0.08191 kg/mol

KBO2: percent composition by element

• Boron (B) = 10.811 : 81.9081 * 100 = 13.199 %
• Potassium (K) = 39.0983 : 81.9081 * 100 = 47.734 %
• Oxygen (O) = 31.9988 : 81.9081 * 100 = 39.067 %
