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.
