Molar and molecular weight of SiC

• Molecular formula: SiC or CSi
• Relative molecular weight of SiC: 40.0962
• Molar mass of SiC: 40.0962 g/mol (0.0401 kg/mol)

Calculation of the relative molecular and molar mass of SiC

• Mr[SiC] = Ar[C] + Ar[Si] = 12.0107 + 28.0855 = 40.0962
• Molar mass (kg/mol) = Mr[SiC] : 1000 = 40.0962 : 1000 = 0.0401 kg/mol

SiC: percent composition by element

• Carbon (C) = 12.0107 : 40.0962 * 100 = 29.955 %
• Silicon (Si) = 28.0855 : 40.0962 * 100 = 70.045 %
