.

Quizplus · Accepted Answer

First, we need to convert the mass of KCl into moles:

24.7 g KCl x (1 mol KCl/74.55 g KCl) = 0.332 mol KCl

Next, we need to calculate the volume of the solution in liters:

11.2 mL = 11.2/1000 L = 0.0112 L

Finally, we can calculate the molarity:

Molarity = moles of solute/volume of solution in liters

Molarity = 0.332 mol/0.0112 L = 0.663 M

Therefore, the answer is B.
