Molar and molecular weight of UCl6

• Molecular formula: UCl6 or Cl6U
• Relative molecular weight of UCl6: 450.74691
• Molar mass of UCl6: 450.74691 g/mol (0.45075 kg/mol)

Calculation of the relative molecular and molar mass of UCl6

• Mr[UCl6] = Ar[Cl] * 6 + Ar[U] = 35.453 * 6 + 238.02891 = 450.74691
• Molar mass (kg/mol) = Mr[UCl6] : 1000 = 450.74691 : 1000 = 0.45075 kg/mol

UCl6: percent composition by element

• Chlorine (Cl) = 212.718 : 450.74691 * 100 = 47.192 %
• Uranium (U) = 238.02891 : 450.74691 * 100 = 52.808 %
