Molar and molecular weight of CH3CHO

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

Calculation of the relative molecular and molar mass of CH3CHO

• Mr[CH3CHO] = Ar[C] * 2 + Ar[H] * 4 + Ar[O] = 12.0107 * 2 + 1.00794 * 4 + 15.9994 = 44.05256
• Molar mass (kg/mol) = Mr[CH3CHO] : 1000 = 44.05256 : 1000 = 0.04405 kg/mol

CH3CHO: percent composition by element

• Carbon (C) = 24.0214 : 44.05256 * 100 = 54.529 %
