Molar and molecular weight of O2F2

• Relative molecular weight of O2F2: 69.9956064
• Molar mass of O2F2: 69.9956064 g/mol (0.07 kg/mol)

Calculation of the relative molecular and molar mass of O2F2

• Mr[O2F2] = Ar[O] * 2 + Ar[F] * 2 = 15.9994 * 2 + 18.9984032 * 2 = 69.9956064
• Molar mass (kg/mol) = Mr[O2F2] : 1000 = 69.9956064 : 1000 = 0.07 kg/mol

O2F2: percent composition by element

• Oxygen (O) = 31.9988 : 69.9956064 * 100 = 45.715 %
• Fluorine (F) = 37.9968064 : 69.9956064 * 100 = 54.285 %
