When processing titration results, what do you do with results that are very close together? 1)Take an average
2)Pick one
3)ignore them

The volume and concentration of base equals the number of moles of base. This is use to determine the number of moles of acid in the flask. Since you are interested in the number of moles of acid in the flask, why would adding water (which doesn't have any acid) change the number of moles of acid?

you need to give more information

its first and third is your answer i did the qustion the fourth isnt right
