Molar and molecular weight of NiO

• Relative molecular weight of NiO: 74.6928
• Molar mass of NiO: 74.6928 g/mol (0.07469 kg/mol)

Calculation of the relative molecular and molar mass of NiO

• Mr[NiO] = Ar[Ni] + Ar[O] = 58.6934 + 15.9994 = 74.6928
• Molar mass (kg/mol) = Mr[NiO] : 1000 = 74.6928 : 1000 = 0.07469 kg/mol

NiO: percent composition by element

• Nickel (Ni) = 58.6934 : 74.6928 * 100 = 78.58 %
• Oxygen (O) = 15.9994 : 74.6928 * 100 = 21.42 %
