This problem involves a titration experiment and calculations related to a monobasic acid HY.

(a):
This part requires performing an experiment, tabulating burette readings (initial and final), calculating the volume of A used for each titration, and then determining the average volume of A. Since no experimental data (burette readings) is provided, this part cannot be solved numerically.

(b):
To perform the calculations in this section, we need an average volume of acid A (HY) used in the titration. As no experimental data is provided, we will assume a common pipette volume for B (NaOH) and a plausible average titre volume for A (HY) to demonstrate the calculations.
Let's assume
