# Calculating Average Molarity of 0.1M NaOH after Titration

I have a big Chemistry test Friday, and I have to learn how to find the average molarity of NaOH (0.1 M) from three trial titration experiments I did in lab.

Titration #1

Volume of NaOH used =3.9 ml

Titration #2

Volume of NaOH used = 3.9 ml

Titration #3

Volume of NaOH used = 4.0 ml.........AVERAGE MOLARITY OF NaOH_________M?

I have to show my calculations on the exam, but my text doesn't show how to find the average molarity. I'm a bit lost on this one and could really use some help to anyone willing. I really need to see every step so I can understand what I'm doing. Thanks!
