Derive the formula of hydrochloric acid, if by burning it with a mass of 13.6 g, carbon monoxide (IV)

Derive the formula of hydrochloric acid, if by burning it with a mass of 13.6 g, carbon monoxide (IV) with a volume of 22.4 liters and water with a mass of 14.4 g were obtained. the hydrogen vapor density of the substance is 34.

Explanation: we find the molar mass of an unknown hydrocarbon, draw up the reaction equation in general form, it can be seen that all the carbon from the compound has gone into carbon dioxide, and hydrogen into water, so you can compose the corresponding half-reactions.
For carbon and hydrogen, we find the amount of matter, and then it is necessary to calculate their ratio (by the amount of matter), so we found the coefficients. Finally, you need to compare the molar mass of the resulting compound.
