Question

question 9 of 10
what is the molarity of 6 moles (mol) of nacl dissolved in 2 l of water?

a. \\(\frac{6\\ l}{2\\ mol}\\)

b. \\(\frac{6\\ mol}{2\\ l}\\)

c. \\(\frac{2\\ mol}{6\\ l}\\)

d. \\(\frac{2\\ l}{6\\ mol}\\)

Explanation:

Step1: Recall Molarity Formula

Molarity ($M$) is defined as moles of solute divided by liters of solution, so $M = \frac{\text{moles of solute}}{\text{volume of solution (in L)}}$.

Step2: Identify Values

Moles of NaCl (solute) = 6 mol, Volume of water (solution) = 2 L.

Step3: Apply Formula

Substitute values into the formula: $M = \frac{6\ \text{mol}}{2\ \text{L}}$.

Answer:

B. $\frac{6\ \text{mol}}{2\ \text{L}}$
