We did a lab and have to answer the following question: What was the concentration of the NaOH solution? Show your calculations. If you did not use all of your data, explain why. This is the data that was obtained by the lab during 3 trials: KHP masses (g) --> 1 2 3 0.61 .061 0.65 Titration of KHP Run 1 Run 2 Run 3 original volume 40.20 mL 40.10 mL 40.20 mL final volume 6.89 mL 0.00 mL 0.00 mL volume used (final-initial) 33.31 mL 40.10 mL 40.20 mL concentration of NaOH (M) avg: concentration of NaOH (M) : also, should the values for volume used be negative or are they correct as is? And I'm not sure how to find the concentration from the values my lab group and I got.

We did a lab and have to answer the following question:
What was the concentration of the NaOH solution? Show your calculations. If you did not use all of your data, explain why.
This is the data that was obtained by the lab during 3 trials:
KHP masses (g) -->
| 1 | 2 | 3 |
| 0.61 | .061 | 0.65 |
Titration of KHP
| Run 1 | Run 2 | Run 3 | |
| original volume | 40.20 mL | 40.10 mL | 40.20 mL |
| final volume | 6.89 mL | 0.00 mL | 0.00 mL |
| volume used (final-initial) | 33.31 mL | 40.10 mL | 40.20 mL |
| concentration of NaOH (M) |
avg: concentration of NaOH (M)
: also, should the values for volume used be negative or are they correct as is? And I'm not sure how to find the concentration from the values my lab group and I got.
