What is the density of an object having a mass of 5.0g and a volume of 45.0 cm^3?
That makes sense. Can you give me an example of a high-density material and a low-density material?
Sure! A high-density material would be lead, which has a density of 11.3 g/cm^3, while a low-density material would be helium gas, which has a density of 0.1785 g/L at room temperature and pressure.
