Answer

To continue with the problem, we need to assume an average volume of A used from the burette, as no experimental data was provided. We will also assume the volume of B used in the pipette.

Assumptions:

  • Volume of B (KOH\text{KOH}) used in each titration = 20.0 cm320.0 \text{ cm}^3
  • Average volume of A (CH3COOH\text{CH}_3\text{COOH}) used = 20.50 cm320.50 \text{ cm}^3

Step 1: Calculate the moles of CH3COOH\text{CH}_3\text{COOH} (A) used.
The concentration of A is 0.100 mol dm−30.100 \text{ mol dm}^{-3}.
The average volume of A used is $20.50
