Answer:

The answer is B) 0.67 M.

Refer to the explanation for the process.

Explanation:

#"Molarity (M)"="moles of solute"/"liters of solution"#

The mol #"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).

#750cancel"mL"xx(1"L")/(1000cancel"mL")="0.75 L"#

Now you can calculate the molarity of the solution.

#"Molarity MgCl"_2=("0.50 mol MgCl"_2)/(0.75"L")="0.67 mol "/"L"="0.67 M"#
