Question

What is the molarity of a solution prepared by dissolving potassium hydroxide (KOH) in some water and then diluting the solution to a volume of .5 L ?

Answer 1

whats the mass of KOH?

Answer 2

The molar mass is 56.1g but they don't give us any mass in the original problem.

Answer 3

Ok I can't figure out without a mass or number of moles of KOH

Answer 4

ok thanks for trying, I appreciate

Answer 5

The best I can do for you is write a generic equation for you

\[\frac{n-moles}{.5L}=Molarity\]

n is simply the number of moles

Answer 6

thank you, I got it now!!
