Answer: 0.455 moles of chlorine gas is formed.
Step-by-step explanation:
We are given:
Moles of HCl = 1.82 moles
The chemical equation for the reaction of
and HCl follows:

By Stoichiometry of the reaction:
If 4 moles of HCl produces 1 mole of chlorine gas
So, 1.82 moles of HCl will produce =
of chlorine gas
Hence, 0.455 moles of chlorine gas is formed.
