Question
g 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 acetone, carbon tetrachloride, dimethyl sulfoxide, ethanolamine, and tetrahydrofuran. The chemist plans to try to identihy the unknown liqui y measuring the density and comparing to known densties. First, from his collection of Data Sheets (MSDS), the chemist finds the following information: liquid density acetone 0.79 mL carbon tetrachlonde 16 mL ethanolamine 1.0 mL tetrahydrofuran 10.89 mL Next, the chemist measures the volume of the unknown liquid as 1338, em and the mass of the unknown liquid as 1.69 kg. Calculate the density af the liquid. Round yourml answer to 3 significant digits Gliven the data above, is it possible to identily yes the liquid? carbon tetrachloride dimethyl sulfoxide ir in is possible to identify the liquid, do soExplanation / Answer
Answer:-
Volume of the unknown liquid = 1338 cm3
= 1338 mL
mass of unknown liquid = 1.69 kg
= 1.69 x 103 g
= 1690 g
Density of unknown liquid = mass/volume
= 1690/1338
=1.26 g/mL
No, it is not possible to identify the liquid.
