Molar and molecular weight of CH2O

• Relative molecular weight of CH2O: 30.02598
• Molar mass of CH2O: 30.02598 g/mol (0.03003 kg/mol)

Calculation of the relative molecular and molar mass of CH2O

• Mr[CH2O] = Ar[C] + Ar[H] * 2 + Ar[O] = 12.0107 + 1.00794 * 2 + 15.9994 = 30.02598
• Molar mass (kg/mol) = Mr[CH2O] : 1000 = 30.02598 : 1000 = 0.03003 kg/mol

CH2O: percent composition by element

• Carbon (C) = 12.0107 : 30.02598 * 100 = 40.001 %
• Hydrogen (H) = 2.01588 : 30.02598 * 100 = 6.714 %
• Oxygen (O) = 15.9994 : 30.02598 * 100 = 53.285 %
