Answer:

0.25M

Explanation:

We can apply the following formula to find molarity ,since the Molarity (M) is the number of moles of solute per liter of solution.  

[tex]Molarity=\frac{mol}{L}[/tex]

[tex]mol=0.50mol[/tex] of KI(potassium iodide)

[tex]L=2.0liters[/tex]

we can substitute the values to find the molarity

[tex]Molarity=\frac{mol}{L}\\Molarity=\frac{0.50mol}{2.0liters} \\Molarity=0.25M[/tex]

So the molarity of 2.0 liters of an aqueous solution that contains 0.50 mol of potassium iodide is 0.25M

Answer:

[tex]0.25moldm^{-3}[/tex]

Explanation:

Molarity could be defined as the amount of solute (in moles) dissolved in  1 litre of water to give its solution. It can also be referred to as the concentration of the resulting solution.

The molarity is thus calculated as follows;

[tex]1litre=1dm^{-3}\\hence\\2litres=2dm^{-3}[/tex]

[tex]molarity=\frac{0.5mole}{2dm^{3}}\\molarity=0.25moldm^{-3}[/tex]
