The unit cell of copper corresponds to a face centered cube of edge length 3 . 596 Å with one copper atom at each lattice point. The calculated density of copper in kg / m 3 is ___ . [Molar mass of Cu : 63 . 54 g ; Avogadro Number = 6 . 022 × 10 23 J ]

Correct answer

0

Step-by-step solution

FCC, d = Z × M N A × a 3 = 4 × 63 . 54 1000 × 6 . 022 × 10 23 × 3 . 596 × 10 - 10 3 = 9076   kg / m 3
