Molar and molecular weight of F4Si

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

Calculation of the relative molecular and molar mass of F4Si

• Mr[F4Si] = Ar[F] * 4 + Ar[Si] = 18.9984032 * 4 + 28.0855 = 104.0791128
• Molar mass (kg/mol) = Mr[F4Si] : 1000 = 104.0791128 : 1000 = 0.10408 kg/mol

F4Si: percent composition by element

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