Question

please solving this problem okkkkkkkkkk​

Answer 1

Answer:

Explanation:

FACE CENTERED CUBE , Z= 1/8*8+1/2*6

                                             = 1+3

                                             = 4

EDGE LENGTH ,A = 408 PM

                              = 408*10^-12 M

MOLAR MASS = 197 G / MOL

DENSITY = Z* MOLECULAR MASS/ A³* NA [ NA = AVOGADRO NUMBER]

DENSITY = 4*197/(408*10^-12)³*602*10^23

               = 190* 10^4.

HOPE THIS HELPS.
