Molar and molecular weight of CoO

• Relative molecular weight of CoO: 74.932595
• Molar mass of CoO: 74.932595 g/mol (0.07493 kg/mol)

Calculation of the relative molecular and molar mass of CoO

• Mr[CoO] = Ar[Co] + Ar[O] = 58.933195 + 15.9994 = 74.932595
• Molar mass (kg/mol) = Mr[CoO] : 1000 = 74.932595 : 1000 = 0.07493 kg/mol

CoO: percent composition by element

• Cobalt (Co) = 58.933195 : 74.932595 * 100 = 78.648 %
• Oxygen (O) = 15.9994 : 74.932595 * 100 = 21.352 %
