Acrylic and PVC are both types of plastic, but they’re different compounds. Acrylic has the chemical formula C5O2H8 meaning it is made of 5 carbon atoms, 2 oxygen atoms, and 8 hydrogen atoms. PVC has the chemical formula C2H3Cl. Compare the masses of the atoms that make up these plastics and come up with an explanation as to why PVC is more dense than acrylic
