A student carried out a titration to find the concentration of a sodium hydroxide solution. The table below shows their results.
| Rough titration | Accurate titration 1 | Accurate titration 2 | Accurate titration 3 | |
|---|---|---|---|---|
| Final reading on burette in cm3\text{cm}^3cm3 | 23.40 | 22.90 | 23.85 | 22.15 |
| Initial reading on burette in cm3\text{cm}^3cm3 | 1.10 | 1.55 | 2.40 | 0.75 |
| Volume of sodium hydroxide solution added in cm3\text{cm}^3cm3 | 21.35 | 21.45 | 21.40 |
Calculate the mean volume of sodium hydroxide solution used in the accurate titrations.
