I second that Stine.. I'll give you guys a hint, it has partiality to do with Conflict Theory.

So, Mols NaOH = 0.2264 M NaOH x 0.04936 L NaOH = 0.011175 Mols KHP = grams KHP / molar mass KHP or grams KHP = Mols KHP x molar mass KHP so 0.011175 x 204.22 = 2.2822 grams of KHP Is that correct DBob222?

I figured it out if it contains the conjugate base of a strong acid

Or if you didn't correct this error, the molarity of the base would be higher than it should be. Is that correct?

Oops, I mean the molarity would decrease because moles base / larger quantity in L = a small # therefore decreased molarity. Correct?

Got the answer thanks anyway
