Molar and molecular weight of H4Si

• Molecular formula: H4Si or SiH4
• Relative molecular weight of H4Si: 32.11726
• Molar mass of H4Si: 32.11726 g/mol (0.03212 kg/mol)

Calculation of the relative molecular and molar mass of H4Si

• Mr[H4Si] = Ar[H] * 4 + Ar[Si] = 1.00794 * 4 + 28.0855 = 32.11726
• Molar mass (kg/mol) = Mr[H4Si] : 1000 = 32.11726 : 1000 = 0.03212 kg/mol

H4Si: percent composition by element

• Hydrogen (H) = 4.03176 : 32.11726 * 100 = 12.553 %
• Silicon (Si) = 28.0855 : 32.11726 * 100 = 87.447 %
