Question

If 1.80 moles of NaCl was dissolved in enough water to make 3.60 L of solution, what is the Molarity?

Answer 1

Answer:

0.5M

Explanation:

The equation for molarity is:

• M = $\frac{mol}{liters}$ ; where the "M" stands for molarity, the "mol" stands for moles of solute and the "liters" means the volume in liters of solution.

We are given that there are:

• 1.80 moles of NaCl (the moles of solute)

• 3.60 Liters of solution (the volume in liters of solution)

Now we just plug those numbers into the formula and get our answer:

• M= $\frac{1.80mol}{3.60L}$= 0.5M

After doing the math and dividing the moles of solute by the liters of solution, we get that the molarity of the solution is 0.5M.
