0.28 g of a gaseous hydrocarbon was turned in excess oxygen. 0.88 g of carbon dioxide and 0.36 g of water were formed. The volume of 0.28 g of the hydrocarbon at 1.01 x10^5 Pa and 298 k is 123 cm^3. Work out the molecular formula of the hydrocarbon.

For a problem such as this, it is important to break down the question into the individual aspects and use some principles of chemistry that we have learnt previously to tackle the problem one step at a time...
