I know I am over thinking this problem like always but none of this makes sense to me for some reason..

KHP was used to determine the concentration of a KOH solution. If 0.78g of KHPwas used and 42.17 ml of KOH was used to titrate it to the endpoint what's it concentration?
How do I start it?

KHP + KOH ==> K2P + H2O

mols KHP = grams/molar mass = ?
mols KOH = mols KHP (look at the coefficients and see they are 1:1).
Then M KOH = mols KOH/L KOH.
