Molar and molecular weight of Ba(NO2)2

• Molecular formula: Ba(NO2)2 or BaN2O4
• Relative molecular weight of Ba(NO2)2: 229.338
• Molar mass of Ba(NO2)2: 229.338 g/mol (0.22934 kg/mol)

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

• Mr[Ba(NO2)2] = Ar[Ba] + Ar[N] * 2 + Ar[O] * 4 = 137.327 + 14.0067 * 2 + 15.9994 * 4 = 229.338
• Molar mass (kg/mol) = Mr[Ba(NO2)2] : 1000 = 229.338 : 1000 = 0.22934 kg/mol
