5. The accepted values for density are: aluminum = 2.71 g/cm³; PE = about 0.925 g/cm³; and iron = 7.87 g/cm³. Compare your values from Question 4 with these. How do they compare? Why are they different? Note: the density of different kinds of PE and PVC vary because of the difference in the arrangements of their molecules.​
