Answer
The measurements are **neither accurate nor precise**.Here's why:* **Accuracy:** Accuracy refers to how close a measurement is to the true or accepted value. The known mass is 6.68 grams. None of the measurements are particularly close to this value.* **Precision:** Precision refers to how close repeated measurements are to each other. While measurements 3 and 4 are relatively close, measurements 1 and 2 are quite far apart, and none are close to the other pair. This indicates poor precision.Since the measurements are neither close to the true value nor consistently close to each other, they are neither accurate nor precise.
