TlAlSO42 . xH2Ois bcc with edge lengtha= 1.22 nm. If the density of the solid is2.32 g/cc, then the value ofxis
(Given: N A =6× 10 23 , atomtextc weight (in g/mol ) TI=204,Al=27,S=32,O=16,H=1 )

Options:

Answer:
C
Solution:

For any unit cell
d= 2M a 3 N A (for BCC,Z=2)
2.32=2 ×M6×1023×1.223×1021
 M=1264
So 4 2 3 + x 1 8 = 1 2 6 4
x = 4 7
