Molar and molecular weight of Ca(NO2)2

• Molecular formula: Ca(NO2)2 or CaN2O4
• Relative molecular weight of Ca(NO2)2: 132.089
• Molar mass of Ca(NO2)2: 132.089 g/mol (0.13209 kg/mol)

Calculation of the relative molecular and molar mass of Ca(NO2)2

• Mr[Ca(NO2)2] = Ar[Ca] + Ar[N] * 2 + Ar[O] * 4 = 40.078 + 14.0067 * 2 + 15.9994 * 4 = 132.089
• Molar mass (kg/mol) = Mr[Ca(NO2)2] : 1000 = 132.089 : 1000 = 0.13209 kg/mol

Ca(NO2)2: percent composition by element

• Calcium (Ca) = 40.078 : 132.089 * 100 = 30.342 %
• Nitrogen (N) = 28.0134 : 132.089 * 100 = 21.208 %
• Oxygen (O) = 63.9976 : 132.089 * 100 = 48.45 %
