Question

If you dissolve 14.2 grams of licl in enough water to make 0.450 l of solutions, what is the molarity of the solution?

Answer 1

Remember the equation for molarity:

`molarity = (moles)/(volume)`
*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.


`molarity = (0.34moles)/(0.45liters)`
Then, you should get your answer.

Hope that helps!
