1. Density is a physical property of a molecule that’s measured as mass per unit volume. Given that density is usually expressed in the units of g/cm3, calculate the density of a cube of plastic that has a mass of 2.331 g and an edge length of 1.500 cm (volume of a cube is V = l3). Be sure to show all steps in the process and include units throughout the problem.
2. Two liquids are in a graduated cylinder – Liquid A has a density of 1.004 g/cm3 and Liquid B has a density of 0.6223 g/cm3. Assuming that they do NOT mix, which liquid is on top and which liquid is on bottom? Where would you expect to find the plastic cube from Question #1 if it is dropped into the graduated cylinder with these two liquids?
