Answer

Explanation:

Step1: Write the balanced chemical equation

The reaction is (2SO_{2}+O_{2}\rightarrow 2SO_{3}).

Step2: Analyze atom - conservation

In the reactants, we have 2 sulfur atoms and 6 oxygen atoms. In (SO_{3}), each molecule has 1 sulfur atom and 3 oxygen atoms.

Step3: Calculate the number of (SO_{3}) molecules

Since we have 2 sulfur atoms and each (SO_{3}) molecule has 1 sulfur atom, and also considering oxygen - atom conservation (6 oxygen atoms in reactants and 3 oxygen atoms per (SO_{3}) molecule), the number of (SO_{3}) molecules is 2.
