To describe the experiment based on the calculated density values of water (1.00 g/mL, 0.98 g/mL, and 0.99 g/mL) compared to the accepted value of 0.99 g/mL, we can analyze the results in terms of accuracy and precision.
1. **Accuracy**: This refers to how close the measured values are to the accepted or true value. In this case, the accepted density of water at room temperature is 0.99 g/mL. The calculated values of 0.99 g/mL and 0.98 g/mL are very close to this accepted value, indicating that they are accurate. The value of 1.00 g/mL is slightly higher but still reasonably close.
2. **Precision**: This refers to how close the measured values are to each other. The values 1.00 g/mL, 0.98 g/mL, and 0.99 g/mL are fairly close, demonstrating a reasonable level of precision in the measurements.
Considering both accuracy and precision, the best answer to describe this experiment is that it produced **accurate and reasonably precise measurements of the density of water**. The slight variation of the individual measurements indicates good but not perfect precision. Overall, the results reflect a successful experiment in determining the density of water.
