Please provide the missing information for parts (iv) and (v) of the ethanoic acid titration problem.

To solve these problems, I need some additional information from the experiment or previous parts of the question.

For part (iv), please provide:

• The concentration (molarity) of the ethanoic acid.
• The average volume of A used, in $\text{cm}^3$ or $\text{mL}$.

For part (v), please provide:

• The balanced chemical equation for the reaction.
• The moles of any reactant or product involved in the reaction, or enough information to calculate them (e.g., volume and concentration of another reactant).

Once you provide this information, I can proceed with the calculations. Send me the next one 📸
