A flask that contains hexane (d = 0.66 g/mL) and water (d = 1.0 g/mL); these liquids do no mix together. Different materials are added to the flask. Identify the material indicated by the square object in the figure below.

The density of a sample of wine is 1.08 g/mL. If a Salmanazar of wine is 9.00 liters, what is the weight of 3.67 Salmanazar of wine in ounces?

List a potassium cube (density = 0.862 g/cm3), a cesium cube (density = 1.9 g/cm³), and a rubidium cube (density = 1.63 g/cm³), that have similar masses, from smallest to largest

Two types of sand are to be separated using the difference in density in a liquid. Sand A has a density of 1.21 g/cm³ and sand B has a density of 2.93 g/cm³.

The two sand samples will be placed in a container and mixed well with the liquid. Upon settling, the denser materials will be at the bottom and the less dense material will float to the top.

Given the following unreactive liquids and their densities, identify which of them would be a good option for the separation.

Liquid A (2.63 g/cm³)

Liquid B (1.51 g/cm³)

Liquid C (0.95 g/cm³)

Liquid D (1.96 g/cm³)

A student needs cyclohexane for an experiment. They asked their lab partner to get it from the storage cabinet. The lab partner then handed an unlabeled bottle and told them that it was the bottle for cyclohexane that they used in the last experiment. To be sure, they measured 15 mL of the liquid and found that it weighs 26.2 g. A chemistry textbook listed cyclohexane to have a density of 0.773 g/mL at room temperature. Is it possible that the liquid is cyclohexane?

A small airplane takes on 245 L of fuel. If the density of the fuel is 0.761 g/mL, what mass of fuel has the airplane taken on?
