Element	Total atoms	Atomic mass	Total mass
Fe (Iron)	1	55.845	55.845
N (Nitrogen)	3	14.0067	42.0201
O (Oxygen)	9	15.9994	143.9946
			241.8597

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

Mr[Fe(NO3)3] = Ar[Fe] + Ar[N] * 3 + Ar[O] * 9 = 55.845 + 14.0067 * 3 + 15.9994 * 9 = 241.8597
Molar mass (kg/mol) = Mr[Fe(NO3)3] : 1000 = 241.8597 : 1000 = 0.24186 kg/mol

Fe(NO3)3: percent composition by element

Iron (Fe) = 55.845 : 241.8597 * 100 = 23.09 %
