An element crystallizes in a face-centered cubic unit cell has a density of 1.45 g/cm3. The edge length of its unit cell is 4.52 x 10-8cm. What is the approximate atomic mass of the element in g/mol?51
23. If a unit cell of an ionic compound has A cations at the corners and X anions on the face centers, what is the empirical formula of the compound?24. Which substance would you expect to have the lowest boiling point?25. If a unit cell of an ionic compound has “A” cations at the corners and the face centers and“X” anions in the centers of the edges of the unit cells, what is the empirical formula of the compound?26. What is the primaryintermolecular force in a sample of CH2Cl2?27. Which statement is true?52
28. Which answer lists allof the intermolecular forces present in an a sample of NH329. How many atoms are contained in the cubic unit cell depicted below?30. The DNA double helix at the atomic level looks like a twisted ladder, where the "rungs" of the ladder consist of molecules that are attracted to each other. Sugar and phosphate groups make up the sides of the ladder. Shown are the structures of the adenine-thymine (AT) "base pair" and the guanine-cytosine (GC) "base pair."AT base pairGC base pairWhich base pair is more stable to heating?31. Which of these is leastlikely to exist as discrete molecules?53
