Answer :
Final answer:
The most precise set of measurements for an object is the one that has the least amount of variation between measures, in the given options, that is Set C: 2.05 g, 2.04 g, 2.05 g.
Explanation:
To determine which set of measurements of a 2.00-g object is the most precise, we need to define what precision is in the context of measurements. Precision refers to how close the measurements are to each other. The closer the measurements, the higher the precision.
Given the sets of measurements: A) 2.00 g, 2.03 g, 1.98 g B) 2.10 g, 2.00 g, 2.20 g C) 2.05 g, 2.04 g, 2.05 g D) 1.50 g, 2.00 g, 2.50 g - Option C is the most precise. The measurements in Option C are the closest to each other with a minimal variation in measurements, hence showing the greatest degree of precision.
Remember that precision does not mean that the measurements are necessarily accurate or correct. Accuracy is a different concept that relates to how close a measurement is to the actual or true value.
