The answer is B) 0.67 M.

Refer to the explanation for the process.

#### Explanation:

$\text{Molarity (M)"="moles of solute"/"liters of solution}$

The mol ${\text{MgCl}}_{2}$ has been given as $0.50$.

The volume of the solution is in milliliters (mL) and needs to be converted to liters (L).

$750 \cancel{\text{mL"xx(1"L")/(1000cancel"mL")="0.75 L}}$

Now you can calculate the molarity of the solution.

$\text{Molarity MgCl"_2=("0.50 mol MgCl"_2)/(0.75"L")="0.67 mol "/"L"="0.67 M}$
