Molar and molecular weight of CoB

• Molecular formula: CoB or BCo
• Relative molecular weight of CoB: 69.744195
• Molar mass of CoB: 69.744195 g/mol (0.06974 kg/mol)

Calculation of the relative molecular and molar mass of CoB

• Mr[CoB] = Ar[B] + Ar[Co] = 10.811 + 58.933195 = 69.744195
• Molar mass (kg/mol) = Mr[CoB] : 1000 = 69.744195 : 1000 = 0.06974 kg/mol

CoB: percent composition by element

• Boron (B) = 10.811 : 69.744195 * 100 = 15.501 %
• Cobalt (Co) = 58.933195 : 69.744195 * 100 = 84.499 %
