Molar and molecular weight of EuCl2

• Molecular formula: EuCl2 or Cl2Eu
• Relative molecular weight of EuCl2: 222.87
• Molar mass of EuCl2: 222.87 g/mol (0.22287 kg/mol)

Calculation of the relative molecular and molar mass of EuCl2

• Mr[EuCl2] = Ar[Cl] * 2 + Ar[Eu] = 35.453 * 2 + 151.964 = 222.87
• Molar mass (kg/mol) = Mr[EuCl2] : 1000 = 222.87 : 1000 = 0.22287 kg/mol

EuCl2: percent composition by element

• Chlorine (Cl) = 70.906 : 222.87 * 100 = 31.815 %
• Europium (Eu) = 151.964 : 222.87 * 100 = 68.185 %
