Polyethylene can crystalline in crystallites with the chains aligned in an orthorhombic unit cell with dimensions of 740 pm x 493 pm x 253 pm. Each unit cell contains two complete repeating units of CH:CH2. Calculate the crystallographic theoretical density of fully crystalline polyethylene. Look up a literature value for the density of high density polyethylene (HDPE) and compare to your answer.
