Question

A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. Calculate the density of the liquid. Round your answer to 3 significant digits. If it is possible to identify the liquid, do so.

a) Density = 1.48 g/mL, Possible to identify: Yes, Liquid: Chloroform
b) Density = 1.48 g/mL, Possible to identify: No
c) Density = 1.48 g/mL, Possible to identify: Yes, Liquid: Ethanolamine
d) Density = 1.48 g/mL, Possible to identify: Yes, Liquid: Dimethyl sulfoxide

Answer 1

The density of the liquid is 1.033 g/cm³, but we cannot determine its identity based on density alone.

Step-by-step explanation:

The density of a liquid can be calculated by dividing its mass by its volume. In this case, the liquid has a mass of 31.1415 g and a volume of 30.13 cm³. To find the density, divide the mass by the volume: density = mass / volume. Plugging in the values, we get density = 31.1415 g / 30.13 cm³ = 1.033 g/cm³.

The density of the liquid is 1.033 g/cm³. Unfortunately, we cannot determine the identity of the liquid based on its density alone.
