Question

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 carbon tetrachloride, glycerol, diethylamine, methyl acetate, and acetone. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid carbon tetrachlonde 16g.m glycerol 13 g.ml"1 diethylamine 0.71 g mL methyl acetate 093 g.mL 0.79 g mL Next, the chemist measures the volome of the unknown liquid as 1617, cm and the mass of the unknown liquid as 1.01 kg. Calculate the density of the liquid. Be sure your ansver has the correct number of s ml O no tf ia is possible to identify the liquid, do so. methyl acetae

Explanation / Answer

density = mass / volume

mass = 1.01*10^3 g

volume = 1617 cm^3

density = 1.01*10^3/1617

   = 0.625 g/ml

it is not possible to identify the liquid.
