Why can the length of the pin shown in Fig. 2.5 not be recorded as 2.850 cm?
Hexane (C6H14, density = 0.766 g/cm3), perfluoro-hexane (C6F14, density = 1.669 g/cm3), and water are immiscible liquids; that is, they do not dissolve in one another. You place 10 mL of each in a graduated cylinder, along with pieces of high-density polyethylene (HDPE, density = 0.97 g/cm3), polyvinyl chloride(PVC, density = 1.36 g/cm3), and Teflon (density = 2.3 g/cm3). None of these common plastics dissolves in these liquids. Describe what you expect to see.

-If ethanol (S.G. = 0.790) were used rather than water in measuring the density of the irregular objects, how would that have affected the result? Explain. -When you were measuring the volume of the irregular solid you were told to stir to eliminate bubbles. If the bubbles were not eliminated, how would that affect the density? Explain. -Suppose the density of 65.0 mL of some liquid was found to be 0.748 g/mL. What would be the specific gravity of 45.0 mL of this liquid?
