Molar and molecular weight of XeF2

• Molecular formula: XeF2 or F2Xe
• Relative molecular weight of XeF2: 169.2898064
• Molar mass of XeF2: 169.2898064 g/mol (0.16929 kg/mol)

Calculation of the relative molecular and molar mass of XeF2

• Mr[XeF2] = Ar[F] * 2 + Ar[Xe] = 18.9984032 * 2 + 131.293 = 169.2898064
• Molar mass (kg/mol) = Mr[XeF2] : 1000 = 169.2898064 : 1000 = 0.16929 kg/mol

XeF2: percent composition by element

• Fluorine (F) = 37.9968064 : 169.2898064 * 100 = 22.445 %
