Molar and molecular weight of CH4O

• Molecular formula: CH4O or CH3OH
• Relative molecular weight of CH4O: 32.04186
• Molar mass of CH4O: 32.04186 g/mol (0.03204 kg/mol)

Calculation of the relative molecular and molar mass of CH4O

• Mr[CH4O] = Ar[C] + Ar[H] * 4 + Ar[O] = 12.0107 + 1.00794 * 4 + 15.9994 = 32.04186
• Molar mass (kg/mol) = Mr[CH4O] : 1000 = 32.04186 : 1000 = 0.03204 kg/mol

CH4O: percent composition by element

• Carbon (C) = 12.0107 : 32.04186 * 100 = 37.484 %
• Hydrogen (H) = 4.03176 : 32.04186 * 100 = 12.583 %
• Oxygen (O) = 15.9994 : 32.04186 * 100 = 49.933 %
