Molar and molecular weight of SiCl4

• Molecular formula: SiCl4 or Cl4Si
• Relative molecular weight of SiCl4: 169.8975
• Molar mass of SiCl4: 169.8975 g/mol (0.1699 kg/mol)

Calculation of the relative molecular and molar mass of SiCl4

• Mr[SiCl4] = Ar[Cl] * 4 + Ar[Si] = 35.453 * 4 + 28.0855 = 169.8975
• Molar mass (kg/mol) = Mr[SiCl4] : 1000 = 169.8975 : 1000 = 0.1699 kg/mol

SiCl4: percent composition by element

• Chlorine (Cl) = 141.812 : 169.8975 * 100 = 83.469 %
• Silicon (Si) = 28.0855 : 169.8975 * 100 = 16.531 %
