TlAlSO42 . xH2Ois bcc with edge length‘a’= 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 =  2 M a 3   N A (for BCC, Z = 2)
2.32=2 ×M6×1023×1.223×10–21
∴ M=1264
So 4 2 3 + x 1 8 = 1 2 6 4
x = 4 7
