Molar and molecular weight of C2H3

• Relative molecular weight of C2H3: 27.04522
• Molar mass of C2H3: 27.04522 g/mol (0.02705 kg/mol)

Calculation of the relative molecular and molar mass of C2H3

• Mr[C2H3] = Ar[C] * 2 + Ar[H] * 3 = 12.0107 * 2 + 1.00794 * 3 = 27.04522
• Molar mass (kg/mol) = Mr[C2H3] : 1000 = 27.04522 : 1000 = 0.02705 kg/mol

C2H3: percent composition by element

• Carbon (C) = 24.0214 : 27.04522 * 100 = 88.819 %
• Hydrogen (H) = 3.02382 : 27.04522 * 100 = 11.181 %
