How do i work this chemistry problem?

Sylvester Student weighed out 3.0005 g of KHP, transferred it into a 500-mL volumetric flask, and diluted the sample to volume with deionized water. He then pipetted 100 mL of this solution into a 250 ml beaker for a subsequent titration with 0.1009 M NaOH. Calculate the volume of NaOH (in mL) required for Sylvester to reach the theoretical end point (Ve).
