When weighing approximately 5 grams of NaCl, what range should be recorded according to laboratory procedures?

When weighing approximately 5 grams of NaCl, the appropriate range to record is 5.00 to 5.05 grams. This range indicates a precise measurement reflecting the expected value while allowing for slight variations that might occur during the weighing process. In a laboratory setting, particularly when working with mass measurements, it is crucial to consider the accuracy and precision of the balance used, as well as the potential for minor errors in the weighing process.

Recording a range such as 5.00 to 5.05 grams acknowledges these minor fluctuations and provides a more realistic representation of the measurement. Precise measurements are critical for reproducibility and validity in experiments, ensuring that results are reliable and can be compared effectively. Additionally, maintaining a standard practice of recording data in this way reinforces consistency across different experiments and laboratories.
