Combustion of carbon compound

Chemistry Level 2

Chemical substance X is a compound of carbon and hydrogen. At a certain constant temperature and pressure, \(1\) L of substance X was completely combusted, producing \(3\) L of carbon dioxide (\(\text{CO}_2\)) and \(4\) L of vapor (\(\text{H}_2\text{O}\)). Which of the following statements is correct about this reaction?

a) The molecular formula of X is \(C_3H_8\).

b) The volume of gas mixture is increased after the reaction.

c) The mass of oxygen required for a complete combustion of \(4.4\) g of X is \(16\) g.
