Molar and molecular weight of LaN3O9

• Molecular formula: LaN3O9 or La(NO3)3
• Relative molecular weight of LaN3O9: 324.92017
• Molar mass of LaN3O9: 324.92017 g/mol (0.32492 kg/mol)

Calculation of the relative molecular and molar mass of LaN3O9

• Mr[LaN3O9] = Ar[La] + Ar[N] * 3 + Ar[O] * 9 = 138.90547 + 14.0067 * 3 + 15.9994 * 9 = 324.92017
• Molar mass (kg/mol) = Mr[LaN3O9] : 1000 = 324.92017 : 1000 = 0.32492 kg/mol

LaN3O9: percent composition by element
