Answer: The moles of oxygen gas produced will be 3 moles.
Explanation:
For the given chemical reaction:
[tex]2KClO_3\rightarrow 2KCl+3O_2[/tex]
By Stoichiometry of the reaction:
If 2 moles of potassium chlorate produces 3 moles of oxygen gas.
So, 2 moles of potassium chlorate will produce = [tex]\frac{3}{2}]times 3=3[/tex] moles of oxygen gas.
Hence, the moles of oxygen gas produced will be 3 moles.
