Molar and molecular weight of XeF4

• Molecular formula: XeF4 or F4Xe
• Relative molecular weight of XeF4: 207.2866128
• Molar mass of XeF4: 207.2866128 g/mol (0.20729 kg/mol)

Calculation of the relative molecular and molar mass of XeF4

• Mr[XeF4] = Ar[F] * 4 + Ar[Xe] = 18.9984032 * 4 + 131.293 = 207.2866128
• Molar mass (kg/mol) = Mr[XeF4] : 1000 = 207.2866128 : 1000 = 0.20729 kg/mol

XeF4: percent composition by element

• Fluorine (F) = 75.9936128 : 207.2866128 * 100 = 36.661 %
• Xenon (Xe) = 131.293 : 207.2866128 * 100 = 63.339 %
