How does adding 100ml instead of 50 ml to a solid KHP effect the concentration of NaOH in a titration lab?

this was in a titration lab where we mixed about a gram of solid KHP with distilled water to use in a titration. We are asked how it would effect the sodium hydroxide concentration if there was 100ml addded to the KHP instead of 50ml. And i would say that it would take double the NaOH to titrate. But i am totally confused!
