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 pentane, tetrahydrofuran, carbon tetrachloride, methyl acetate, and ethanolamine. 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 density pentane tetrahydrofuran carbon tetrachloride methyl acetate ethanolamine Next, the chemist measures the volume of the unknown liquid as and the mass of the unknown liquid as . Calculate the density of the liquid. Round your answer to significant digits. Given the data above, is it possible to identify the liquid

Answer 1

Answer:

The liquid can be identified

Explanation:

Given that density is defined as mass per unit volume.

We have the following information regarding the unknown liquid;

Mass= 1.40 kg = 1400 g

Volume = 1378 cm^3 = 1378 ml

Density of unknown liquid = 1400/1378 = 1.012 g/ml this is approximately 1.0 g/ml

It is possible to identify the liquid, the liquid is ethanolamine
