Molar and molecular weight of CH

• Relative molecular weight of CH: 13.01864
• Molar mass of CH: 13.01864 g/mol (0.01302 kg/mol)

Calculation of the relative molecular and molar mass of CH

• Mr[CH] = Ar[C] + Ar[H] = 12.0107 + 1.00794 = 13.01864
• Molar mass (kg/mol) = Mr[CH] : 1000 = 13.01864 : 1000 = 0.01302 kg/mol

CH: percent composition by element

• Carbon (C) = 12.0107 : 13.01864 * 100 = 92.258 %
• Hydrogen (H) = 1.00794 : 13.01864 * 100 = 7.742 %
