Textbook Question
Chapter 1, Problem 1.12A
A 1.000 mL sample of acetone, a common solvent used as a paintremover, was placed in a small vial whose mass was known to be 4.002 g. The following values were obtained when the acetone4tlled vial was weighed: 4.531 g,4.525 g, and 4.537 g. How would you characterize the precision and accuracy of thesemeasurements if the true mass of the acetone was 0.7795 g?
