Assume you dissolve 3.7 g of solid KOH in water to make 300 mL of solution. You then take a 20 mL sample of the previous solution and add it to a volumetric flask. Then water is added to the mark. What is the new molarity?

Please answer quickly if you can help. I can not grasp this concept and this question is due soon for me.

Impossible to answer.  Need to know the volume of the volumetric flask.  Is that information given somewhere?

Sorry.

Yes the volume was 500 mL, but I managed to figure out the problem.

Thanks anyways!
