Molar and molecular weight of C3H2

• Relative molecular weight of C3H2: 38.04798
• Molar mass of C3H2: 38.04798 g/mol (0.03805 kg/mol)

Calculation of the relative molecular and molar mass of C3H2

• Mr[C3H2] = Ar[C] * 3 + Ar[H] * 2 = 12.0107 * 3 + 1.00794 * 2 = 38.04798
• Molar mass (kg/mol) = Mr[C3H2] : 1000 = 38.04798 : 1000 = 0.03805 kg/mol

C3H2: percent composition by element

• Carbon (C) = 36.0321 : 38.04798 * 100 = 94.702 %
• Hydrogen (H) = 2.01588 : 38.04798 * 100 = 5.298 %
