Molar and molecular weight of F2S2

• Molecular formula: F2S2 or SSF2
• Relative molecular weight of F2S2: 102.1268064
• Molar mass of F2S2: 102.1268064 g/mol (0.10213 kg/mol)

Calculation of the relative molecular and molar mass of F2S2

• Mr[F2S2] = Ar[F] * 2 + Ar[S] * 2 = 18.9984032 * 2 + 32.065 * 2 = 102.1268064
• Molar mass (kg/mol) = Mr[F2S2] : 1000 = 102.1268064 : 1000 = 0.10213 kg/mol

F2S2: percent composition by element

• Fluorine (F) = 37.9968064 : 102.1268064 * 100 = 37.206 %
• Sulfur (S) = 64.13 : 102.1268064 * 100 = 62.794 %
