			324.92017

Calculation of the relative molecular and molar mass of La(NO3)3

Mr[La(NO3)3] = Ar[La] + Ar[N] * 3 + Ar[O] * 9 = 138.90547 + 14.0067 * 3 + 15.9994 * 9 = 324.92017
Molar mass (kg/mol) = Mr[La(NO3)3] : 1000 = 324.92017 : 1000 = 0.32492 kg/mol

La(NO3)3: percent composition by element

Lanthanum (La) = 138.90547 : 324.92017 * 100 = 42.751 %
Nitrogen (N) = 42.0201 : 324.92017 * 100 = 12.932 %
Oxygen (O) = 143.9946 : 324.92017 * 100 = 44.317 %
