The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium hydrogen phthalate (abbreviated as KHP). KHP is an acid with one acidic hydrogen and a molar mass of 204.22 g/mol. In the titration, 20.96 mL of the sodium hydroxide solution was required to react with 0.1082 g KHP. Calculate the molarity of the sodium hydroxide.

i got 0.0253M it was wrong

Let NaOH solution be called NaS.

0.1082gKHP/20.96mLNaS x 1molKHP/204gKHP x 1molNaOH/1molKHP x 1000mLNaS/1LNaS = 0.0253 mole NaOH per L.

It does not seem that you were wrong. Did you miscopy something?
