Molar and molecular weight of OF2

• Molecular formula: OF2 or F2O
• Relative molecular weight of OF2: 53.9962064
• Molar mass of OF2: 53.9962064 g/mol (0.054 kg/mol)

Calculation of the relative molecular and molar mass of OF2

• Mr[OF2] = Ar[F] * 2 + Ar[O] = 18.9984032 * 2 + 15.9994 = 53.9962064
• Molar mass (kg/mol) = Mr[OF2] : 1000 = 53.9962064 : 1000 = 0.054 kg/mol

OF2: percent composition by element

• Fluorine (F) = 37.9968064 : 53.9962064 * 100 = 70.369 %
• Oxygen (O) = 15.9994 : 53.9962064 * 100 = 29.631 %
