Question

explain why significant figures represent the precision of a measurement and not its accuracy

Explanation:

Significant figures show the number of reliably - known digits in a measurement. They are based on the measuring instrument's resolution (precision). Accuracy is about how close a measurement is to the true value, while significant figures only reflect the instrument's ability to reproduce a value consistently (precision), not its closeness to the actual value.

Answer:

Significant figures represent the precision of a measurement because they are determined by the measuring device's resolution and indicate the reproducibility of a measurement, not how close the measurement is to the true value (accuracy).
