Molar and molecular weight of UO2F2

• Molecular formula: UO2F2 or F2O2U
• Relative molecular weight of UO2F2: 308.0245164
• Molar mass of UO2F2: 308.0245164 g/mol (0.30802 kg/mol)

Calculation of the relative molecular and molar mass of UO2F2

• Mr[UO2F2] = Ar[F] * 2 + Ar[O] * 2 + Ar[U] = 18.9984032 * 2 + 15.9994 * 2 + 238.02891 = 308.0245164
• Molar mass (kg/mol) = Mr[UO2F2] : 1000 = 308.0245164 : 1000 = 0.30802 kg/mol

UO2F2: percent composition by element

• Fluorine (F) = 37.9968064 : 308.0245164 * 100 = 12.336 %
