Molar and molecular weight of UF4

• Molecular formula: UF4 or F4U
• Relative molecular weight of UF4: 314.0225228
• Molar mass of UF4: 314.0225228 g/mol (0.31402 kg/mol)

Calculation of the relative molecular and molar mass of UF4

• Mr[UF4] = Ar[F] * 4 + Ar[U] = 18.9984032 * 4 + 238.02891 = 314.0225228
• Molar mass (kg/mol) = Mr[UF4] : 1000 = 314.0225228 : 1000 = 0.31402 kg/mol

UF4: percent composition by element

• Fluorine (F) = 75.9936128 : 314.0225228 * 100 = 24.2 %
• Uranium (U) = 238.02891 : 314.0225228 * 100 = 75.8 %
