What is the true volume and experiment value

Answer 1

To determine the true volume and experimental value based on the given data, we can summarize the data provided:

1. **True Volume:** This is a fixed volume that your experiment is trying to measure. In your case, the true volume is provided as **50 ml**.

2. **Experimental Value:** This is typically the mean volume measured from your experimental data. You have a mean value listed as **37.63 ml**. This is considered your experimental value.

### Summary:
- **True Volume:** 50 ml
- **Experimental Value (Mean):** 37.63 ml

If you want to analyze how close the experimental value is to the true volume, you may consider calculating the percentage error:

\[
\text{Percentage Error} = \left( \frac{\text{True Volume} - \text{Experimental Value}}{\text{True Volume}} \right) \times 100
\]

Using the provided values:

\[
\text{Percentage Error} = \left( \frac{50\, \text{ml} - 37.63\, \text{ml}}{50\, \text{ml}} \right) \times 100 \approx 24.74\%
\]

This indicates that the experimental measurement of water volume is approximately 24.74% lower than the true volume of 50 ml.
