We’re being asked to **calculate molarity of a solution containing 5.0 moles of KCl in 2.0x10 ^{3} mL of solution**.

Recall that ** molarity** is the ratio of the moles of solute and the volume of solution (in liters). In other words:

$\overline{){\mathbf{Molarity}}{\mathbf{}}{\mathbf{\left(}}{\mathbf{M}}{\mathbf{\right)}}{\mathbf{=}}\frac{\mathbf{moles}\mathbf{}\mathbf{of}\mathbf{}\mathbf{solute}}{\mathbf{Liters}\mathbf{}\mathbf{of}\mathbf{}\mathbf{solution}}}$

**Given:**

What is the molarity of a solution containing 5.0 moles of KCl in 2.0x10^{3} mL of solution?

a. 2.5 M

b. 1.0 M

c. 10. M

d. 5.0 M

e. 2.0 M
