Molar and molecular weight of ZrB2

• Relative molecular weight of ZrB2: 112.846
• Molar mass of ZrB2: 112.846 g/mol (0.11285 kg/mol)

Calculation of the relative molecular and molar mass of ZrB2

• Mr[ZrB2] = Ar[Zr] + Ar[B] * 2 = 91.224 + 10.811 * 2 = 112.846
• Molar mass (kg/mol) = Mr[ZrB2] : 1000 = 112.846 : 1000 = 0.11285 kg/mol

ZrB2: percent composition by element

• Zirconium (Zr) = 91.224 : 112.846 * 100 = 80.839 %
• Boron (B) = 21.622 : 112.846 * 100 = 19.161 %
