Explanation:
All the question is asking you to do is to add the first and 2nd titration volume (volume added), and there after you will divide by 2.
This is illustrated below:
1st Volume added = 16.60cm3
2nd volume added = 16.55cm3
Average volume added =
(16.60 + 16.55)/2
Average volume added = 16.58cm3
