An analyst performed a titration to determine the concentration of citric acid in a commercial batch of lime juice using a standard sodium hydroxide solution.
Their experimental results are recorded in the table below.
| Rough | Titration 1 | Titration 2 | Titration 3 | |
|---|---|---|---|---|
| Final burette reading in cm3\text{cm}^3cm3 | 24.85 | 24.15 | 48.20 | 24.50 |
| Initial burette reading in cm3\text{cm}^3cm3 | 0.10 | 0.20 | 24.15 | 0.15 |
Calculate the mean concordant titre volume of sodium hydroxide that should be used in subsequent concentration calculations.
