WebbHere's Another Formula to Remember. Theoretical Density = actual density (fresh unit weight) / theoretical x 100 = calculated air content. Since the theoretical density from the lab has no air, you are comparing that laboratory weight to the fresh weight which contains air. The air in the fresh weight sample makes it lighter than the theoretical.
