6) What is the density of NaCl given that and rci = 181pm. Show your calculations below. rNa+ = 102pm Hint: Edge length of an unit cell of NaCl, d = 2rci +2rNa+, Volume = d³ Mass of NaCl unit cell = (58.54g/formula unit) x (# of 'units of NaCl' in a unit cell) 6.022 x 1023 units/ formula unit Density = mass/volume

7The substance with the lowest known boiling point (4 K) is helium, an atomic element that has two electrons. Hydrogen is a diatomic molecule and also has two electrons, but its boiling point is significantly higher, at 20.28 K. (a) What is the dominant intermolecular force between a pair of helium atoms and a pair of H2 molecules? (b) Why do you think H2 has a higher boiling point?
