It varies, depending on the star. In most stars, the most common gas is hydrogen, followed by helium. These are also currently the most common elements in the Universe; but as the Universe uses up its fuel, this situation will change.

Hydrogen and helium
The two main gases that make up a young star are hydrogen and helium. These elements were formed during the Big Bang and are the most abundant elements in the universe.
As the gases in a protostar begin to collapse, the central core begins to heat up due to pressure. As more gases are absorbed, the greater the pressure. Once the temperature of the core reaches 10 million degrees K, hydrogen fusion begins, and the star begins it's life on the main sequence. The star will stay on the main sequence whilst it still has hydrogen to fuse. Once all the hydrogen has been used, the star will drop out of the main sequence. Protostar stage in the stellar evolution. [See related question]

first of all, all the gases from the star can't be vanished as this is a scientific reason.
A star is mainly made up of hot gases, usually. The main gas is normally hydrogen. Also helium is important.
