Need assistance with Gen Chem problem

In summary, the conversation is about calculating normality and a specific problem involving a titration of a NaOH solution with KHP. The formula for normality is given, but the volume of the acid is unknown. The known values are the normality and volume of the base. The person is struggling with how to calculate the volume of the acid and is seeking help from others. The conversation also touches on the topic of missing information in the given problem.

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 NaVa?

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.
