Molar and molecular weight of Ba(NO3)2

• Molecular formula: Ba(NO3)2 or BaN2O6
• Relative molecular weight of Ba(NO3)2: 261.3368
• Molar mass of Ba(NO3)2: 261.3368 g/mol (0.26134 kg/mol)

Calculation of the relative molecular and molar mass of Ba(NO3)2

• Mr[Ba(NO3)2] = Ar[Ba] + Ar[N] * 2 + Ar[O] * 6 = 137.327 + 14.0067 * 2 + 15.9994 * 6 = 261.3368
• Molar mass (kg/mol) = Mr[Ba(NO3)2] : 1000 = 261.3368 : 1000 = 0.26134 kg/mol
