Molar and molecular weight of SiF4

• Molecular formula: SiF4 or F4Si
• Relative molecular weight of SiF4: 104.0791128
• Molar mass of SiF4: 104.0791128 g/mol (0.10408 kg/mol)

Calculation of the relative molecular and molar mass of SiF4

• Mr[SiF4] = Ar[F] * 4 + Ar[Si] = 18.9984032 * 4 + 28.0855 = 104.0791128
• Molar mass (kg/mol) = Mr[SiF4] : 1000 = 104.0791128 : 1000 = 0.10408 kg/mol

SiF4: percent composition by element

• Fluorine (F) = 75.9936128 : 104.0791128 * 100 = 73.015 %
• Silicon (Si) = 28.0855 : 104.0791128 * 100 = 26.985 %
