What purpose does the Artist wheel serve in chemistry?|

A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of glycerol, carbon tetrachloride, pentane, tetrahydrofuran, and acetone. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density glycerol -3 1.3 g-cm - 3 1.6 g cm carbon tetrachloride -3 0.63 g·cm pentane tetrahydrofuran -3 0.89 g·cm -3 0.79 g·cm acetone Next, the chemist measures the volume of the unknown liquid as 0.786 L and the mass of the unknown liquid as 991. g. Calculate the density of the liquid. Round your g. cm answer to 3 significant digits. yes Given the data above, is it possible to identify the liquid? no glycerol carbon tetrachloride pentane If it is possible to identify the liquid, do so. tetrahydrofuran acetone

1 please assist with number one in the picture.  I want to be we are correct. This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl

Pre-lab 1. In your own words, what is accuracy and precision? Why are they important in the clinical lab?
