SUMMARY
The discussion centers on a stoichiometry question regarding gas volumes during a chemical reaction. It establishes that the volume of a gas at standard pressure and temperature (STP) is determined by the number of molecules, leading to the conclusion that the volume of sulfur trioxide ($\ce{SO3(g)}$) remains at $10.0\,\text{dm}^3$ after the reaction. The initial volumes of sulfur dioxide ($\ce{SO2(g)}$) and oxygen ($\ce{O2(g)}$) are $10.0\,\text{dm}^3$ and $6.0\,\text{dm}^3$, respectively, with only $5.0\,\text{dm}^3$ of oxygen being consumed. This confirms the principle of gas volume conservation in stoichiometric reactions.
