Question

The che lans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from hei cwiection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density methyl acetate 0.93 g mL dimethyl sulfoxide .1 g mL 1.3 g mL 0.71 g mL tetrahydrofuran 0.89 g mL ala glycerol Ar diethylamine Next, the chemist measures the volume of the unknown liquid as 1610. cm and the mass of the unknown liquid as 1.14 kg. Calculate the density of the liquid. Round your answer to 3 significant digits. 8 mL Given the data above, is it possible to identify the liquid? yes O no methyl acetate O dimethyl sulfoxide °glycerol If it is possible to identify the liquid, do so.

Explanation / Answer

volume of unknown liquid = 1610cm^3

mass of unknown liquid   = 1.14kg = 1140g

The density of unknown liquid   = mass of unknown liquid/volume of unknown liquid

                                             = 1140g/1610cm^3   = 0.71g/cm^3

                                             Yes

The nunknown liquid is diethylamine = 0.71g/cm^3

if is is possible to identify the liquid do so diethylamine >>>>answer
