Molar and molecular weight of C2H

• Relative molecular weight of C2H: 25.02934
• Molar mass of C2H: 25.02934 g/mol (0.02503 kg/mol)

Calculation of the relative molecular and molar mass of C2H

• Mr[C2H] = Ar[C] * 2 + Ar[H] = 12.0107 * 2 + 1.00794 = 25.02934
• Molar mass (kg/mol) = Mr[C2H] : 1000 = 25.02934 : 1000 = 0.02503 kg/mol

C2H: percent composition by element

• Carbon (C) = 24.0214 : 25.02934 * 100 = 95.973 %
• Hydrogen (H) = 1.00794 : 25.02934 * 100 = 4.027 %
