Molar and molecular weight of WF4

• Molecular formula: WF4 or F4W
• Relative molecular weight of WF4: 259.8336128
• Molar mass of WF4: 259.8336128 g/mol (0.25983 kg/mol)

Calculation of the relative molecular and molar mass of WF4

• Mr[WF4] = Ar[F] * 4 + Ar[W] = 18.9984032 * 4 + 183.84 = 259.8336128
• Molar mass (kg/mol) = Mr[WF4] : 1000 = 259.8336128 : 1000 = 0.25983 kg/mol

WF4: percent composition by element

• Fluorine (F) = 75.9936128 : 259.8336128 * 100 = 29.247 %
• Tungsten (W) = 183.84 : 259.8336128 * 100 = 70.753 %
