Molar and molecular weight of BAs

• Molecular formula: BAs or AsB
• Relative molecular weight of BAs: 85.7326
• Molar mass of BAs: 85.7326 g/mol (0.08573 kg/mol)

Calculation of the relative molecular and molar mass of BAs

• Mr[BAs] = Ar[As] + Ar[B] = 74.9216 + 10.811 = 85.7326
• Molar mass (kg/mol) = Mr[BAs] : 1000 = 85.7326 : 1000 = 0.08573 kg/mol

BAs: percent composition by element

• Arsenic (As) = 74.9216 : 85.7326 * 100 = 87.39 %
• Boron (B) = 10.811 : 85.7326 * 100 = 12.61 %
