Molar and molecular weight of SF6

• Molecular formula: SF6 or F6S
• Relative molecular weight of SF6: 146.0554192
• Molar mass of SF6: 146.0554192 g/mol (0.14606 kg/mol)

Calculation of the relative molecular and molar mass of SF6

• Mr[SF6] = Ar[F] * 6 + Ar[S] = 18.9984032 * 6 + 32.065 = 146.0554192
• Molar mass (kg/mol) = Mr[SF6] : 1000 = 146.0554192 : 1000 = 0.14606 kg/mol

SF6: percent composition by element

• Fluorine (F) = 113.9904192 : 146.0554192 * 100 = 78.046 %
• Sulfur (S) = 32.065 : 146.0554192 * 100 = 21.954 %
