First, let's clarify the titration readings you provided earlier. Assuming "first reading" is the initial burette reading and "second reading" is the final burette reading, we can calculate the volume

Okay, Elward, let's break down these calculations from your exam paper. I'll start with the first few parts of section C, as they are sequential and relate to the titration experiment.

First, let's clarify the titration readings you provided earlier. Assuming "first reading" is the initial burette reading and "second reading" is the final burette reading, we can calculate the volume of titrant used.

• Initial burette reading: $13.23 \text{ mL}$
• Final burette reading: $14.36 \text{ mL}$

The volume of titrant (NaOH) used in the titration is:
