Molar and molecular weight of CH3COOOH

• Molecular formula: CH3COOOH or C2H4O3
• Relative molecular weight of CH3COOOH: 76.05136
• Molar mass of CH3COOOH: 76.05136 g/mol (0.07605 kg/mol)

Calculation of the relative molecular and molar mass of CH3COOOH

• Mr[CH3COOOH] = Ar[C] * 2 + Ar[H] * 4 + Ar[O] * 3 = 12.0107 * 2 + 1.00794 * 4 + 15.9994 * 3 = 76.05136
• Molar mass (kg/mol) = Mr[CH3COOOH] : 1000 = 76.05136 : 1000 = 0.07605 kg/mol

CH3COOOH: percent composition by element

• Carbon (C) = 24.0214 : 76.05136 * 100 = 31.586 %
• Hydrogen (H) = 4.03176 : 76.05136 * 100 = 5.301 %
• Oxygen (O) = 47.9982 : 76.05136 * 100 = 63.113 %
