Question

anonymous · Answer

whats the mass of KOH?

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

ok thanks for trying, I appreciate

anonymous · Answer

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
