The molarity of the solution is equal to 0.500M.
To calculate the molarity of a solution, one must use the value of the amount of moles and the volume, so that:
[tex]M = \frac{mol}{v}[/tex]
So, applying the values given in the question we have:
[tex]M = \frac{1mol}{2L}[/tex]
[tex]M = 0.5mol/L[/tex]
So, the molarity of the solution is equal to 0.500M.
