Molar and molecular weight of C2H4O

• Molecular formula: C2H4O or CH3CHO
• Relative molecular weight of C2H4O: 44.05256
• Molar mass of C2H4O: 44.05256 g/mol (0.04405 kg/mol)

Calculation of the relative molecular and molar mass of C2H4O

• Mr[C2H4O] = Ar[C] * 2 + Ar[H] * 4 + Ar[O] = 12.0107 * 2 + 1.00794 * 4 + 15.9994 = 44.05256
• Molar mass (kg/mol) = Mr[C2H4O] : 1000 = 44.05256 : 1000 = 0.04405 kg/mol
