Significant Figures come from ____________, and are used to describe the level of ____________ . *

Question

A. instruments; accuracy

B. instruments; precision

C. precision; instruments

D. accuracy; instruments

Answer 1

The choice is b. The reasoning is that you cannot get any more precise than the least precise piece of data, and the data originates with the instruments being used. Each instrument has a limit or range of its precision, such a +/- 5.0 mL. So, that tells us how the sig figs are related to the instruments.
