At standard temperature and pressure the molar volume of Cl2 and NH3 gases are 22.06 L and
Question:
(a) Given the different molecular weights, dipole moments, and molecular shapes, why are their molar volumes nearly the same?
(b) On cooling to 160 K, both substances form crystalline solids. Do you expect the molar volumes to decrease or increase on cooling to 160 K?
(c) The densities of crystalline Cl2 and NH3 at 160 K are 2.02g/cm3 and 0.84 g/cm3, respectively. Calculate their molar volumes.
(d) Are the molar volumes in the solid state as similar as they are in the gaseous state? Explain.
(e) Would you expect the molar volumes in the liquid state to be closer to those in the solid or gaseous state?
