A note on the door of the cabinet says the cabinet is used to store bottles of diethylamine, finds pentane, tetrahydrofuran, methyl acetate, and glycerol. 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 H Data Sheets (MSDS), the chemist finds the following information: liquid density diethylamine 0.71 pentane 063 tetrahydrofuran 0.89 methyl acetate 0.93 1.3 glycerol Explanation Check MacBook Air

Explanation / Answer

Density=Mass/Volume

Mass and Volume of the liquid is known,we need to change them into same units as that of the known densities.

Volume = 1704cm3 = 1704mL (1cm3=1mL)

Mass = 1.52kg = 1.52*1000g = 1520g

Density = 1520g/1704mL =0.892g/mL

The density is similar to that of tetrahydrofuran.

The liquid is tetrahydrofuran.
