Molar and molecular weight of B12Zr

• Molecular formula: B12Zr or ZrB12
• Relative molecular weight of B12Zr: 220.956
• Molar mass of B12Zr: 220.956 g/mol (0.22096 kg/mol)

Calculation of the relative molecular and molar mass of B12Zr

• Mr[B12Zr] = Ar[B] * 12 + Ar[Zr] = 10.811 * 12 + 91.224 = 220.956
• Molar mass (kg/mol) = Mr[B12Zr] : 1000 = 220.956 : 1000 = 0.22096 kg/mol

B12Zr: percent composition by element

• Boron (B) = 129.732 : 220.956 * 100 = 58.714 %
• Zirconium (Zr) = 91.224 : 220.956 * 100 = 41.286 %
