Molarity = moles of solute(HCl)
                  ------------------------------------
                   volume of the solution
               
                =   1
                    ------
                     5 
               
                =  0.2M.

Hence option B is correct.
Hope this helps!!

Answer:

B. 0.2 M

Explanation:

Hello,

In this case, by considering that the molarity is defined as:

\(M=\frac{mol_{solute}}{V_{solution}}\)

We replace the given 1 mole of HCl as the moles of the solute and 5 liters as the volume of the solution to obtain the required molarity as shown below:

\(M=\frac{1mol}{5L}=0.2M\)

Therefore, the answer is B. 0.2 M.

Best regards.
