Remember the equation for molarity:
[tex]molarity = \frac{moles}{volume} [/tex]
*note that volume is in liters*


They give you grams (14.3 g), which can give you moles if you divide it by the molar mass of LiCl (about 42.4 g/mole).

14.3g/42.4= 0.34 moles

They also give you volume, already in liters:
0.45L

Now, it's a "plug and chug" question.

[tex]molarity = \frac{0.34moles}{0.45liters} [/tex]
Then, you should get your answer.

Hope that helps!
