Answer:

5.1 M KCl

Explanation:

Moles and liters of a substance are related through the equation

molarity=moles/L

JUst plug in 2.3 moles and 0.45 liters and divide and you get 5.1 (2 SF) moles per liter or M.

Molarity is defined as the number of moles per liter of solution. So 2.3 moles of KCl in 0.45L of solution would be [tex]M=\frac{2.3mol}{0.45L}=5.11M[/tex].
