The rocket's motors account for some of the rest, but the bulk of it consists of the propellants (the fuel and oxidant that react to produce the thrust required to reach orbit) and the gubbins needed to handle these propellants (tanks, pumps, valves, piping and the bodywork that contains them).

But having to carry the propellants needed to create the gas (the reaction mass) is a pain, for at any given moment during a flight the action has to propel not only the rocket itself, but also all of the remaining, unburnt propellant.
