Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. • Sample A is 100. mL of a clear liquid. The liquid is heated in a flask until it boils. The vapor that rises off the boiling liquid is collected for 10 minutes and cooled until it condenses into a separate beaker. The density of the liquid that remains in the flask is then measured, and turns out to be 1.04 g/mL. The density of the liquid that boiled off turns out to be 0.77 g/mL. Sample B is a solid yellow cube with a total mass of 50.0 g. The cube is divided into two smaller 25.0 g subsamples, and the volume of each subsample is measured. The volume of the first is 48.2 cm³ and the volume of the second is 58.1 cm³. When the experiment is repeated with a new 50.0 g. sample, the volume of the two 25.0 g subsamples is 52.2 cm³ and 50.8 cm³.
