Complete combustion of 0.00300 mol of an organic acid produced 0.0120 mol of carbon dioxide.
The same amount of the acid required 15.0 cm3 of 0.400 mol dm−3 NaOH (aq)0.400\text{ mol dm}^{-3}\ \text{NaOH (aq)}0.400 mol dm−3 NaOH (aq) for complete neutralisation.
Which could be the formula of the acid?
CH3CH2CH2COOH\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}CH3CH2CH2COOH
HOOCCH2COOH\text{HOOCCH}_2\text{COOH}HOOCCH2COOH
HOOCCH2CH2COOH\text{HOOCCH}_2\text{CH}_2\text{COOH}HOOCCH2CH2COOH
CH3CH2COOH\text{CH}_3\text{CH}_2\text{COOH}CH3CH2COOH
