Molar and molecular weight of Fe(CNS)3

• Relative molecular weight of Fe(CNS)3: 230.0922
• Molar mass of Fe(CNS)3: 230.0922 g/mol (0.23009 kg/mol)

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

• Mr[Fe(CNS)3] = Ar[Fe] + Ar[C] * 3 + Ar[N] * 3 + Ar[S] * 3 = 55.845 + 12.0107 * 3 + 14.0067 * 3 + 32.065 * 3 = 230.0922
• Molar mass (kg/mol) = Mr[Fe(CNS)3] : 1000 = 230.0922 : 1000 = 0.23009 kg/mol

Fe(CNS)3: percent composition by element
