Need assistance with Gen Chem problem

[RGH]

It has been a long while since I have had to calculate normality. If I remember correctly the formula for normality is:

N=g/(equiv wt x Vol) or NAcidVAcid=NBaseVBase

The known values given are the normality of the base and the volume of the base. Since the normality of the acid is the desired unknown, I am guessing the volume of the acid is given; however I am struggling on how to calculate it. I know I am making this much harder than it should be, but any help you can provide would be greatly appreciated. Well here is the problem.

What is the normality of a NaOH solution if a titration requires 35.17 ml of the solution to neutralize 0.8591 g of KHP? N of NaOH = 0.10.

Thank you,

How many moles of KHP? How is that related to N_aV_a?

You wanted to put this in "Other Sci." in "Homework Help," or in "Chemistry" in the main forum list --- "the next available mod will take care of that for you."

Sorry about putting this in the wrong thread; however, the problem does seem to be missing information (right?). It was one made by the lab TA. I don't think it is solveable. I don't think I forgot to copy something down. Thanks for trying to help though. I am going to bother the TA about it tomorrow.

The TA didn't do your library, or handbook, work for you, but all the information's there --- you can look up MW/FW for KHP.

Start with normality definition. In this particular case normality is identical to molarity.
