(a) Use crystal structure data to determine the density of Cu (an fcc metal with a = 3.615 A), Mo (a bcc metal with a = 3.165 A) and CsCl 4.129 A) and CsCl (a slat with a simple cubic structure with a = 4.129 A). (b) Determine Avogadro’s constant from crystallographic data given that the density of Au is 19.3 g cm^-3 and that it is an fcc metal with a = 4.0786 A.
