What is the molarity of a solution containing 17.0 g of KCl in 213 mL of KCl solution?

Chemistry

Anarel [89]3 years ago

Answer:

1.070MKCl

Explanation:

So we know that the original formula is M= n/L (n being moles of solute, L being liters of solvent)

Since we do not have liters in this problem, we would need to convert  milliliters to liters

<u>213 mL= 0.213 L</u>

We then see that we do not have moles, but we do have a mass, being <u>17.0 g.</u> we would need to convert these grams to moles, giving us <u>0.228 mol.</u>

Then, you would plug in <u>0.228 for your n</u>, and now you are ready to solve your original formula, plugging everything in.

M=n/L

M=0.228 mol/0.213L

M= 1.070MKCl

I know this was long, but I hope this helps (:

Does the antifreeze you put in a car radiator have a lower or higher freezing point than water
saveliy_v [14]
Hello!
Antifreeze says it in the name. This means that it helps prevent freezing. The liquid that would freeze if you wouldnt use the antifreeze is water. This means that the antifreeze has to have a higher freezing point then water, because otherwise it would only freeze faster!

Hope this helped you!
