Question

Determine the molarity of a solution formed by dissolving 3.00 moles of NaCl in                    enough water to yield 4.00 L of solution.

 

                       A) 1.33 M

                       B) 2.00 M

                       C) 0.750 M

                       D) 3.00 M

                       E) 12.00 M

Answer 1

We know,

$Molarity = \dfrac{Number\hspace{2mm} of\hspace{2mm} moles\hspace{2mm} of \hspace{2mm}solute}{Volume \hspace{2mm}of\hspace{2mm} solution\hspace{2mm} in\hspace{2mm} Liter}$

Molarity $= \dfrac{3}{4} = 0.750$ M
