Question

PbS has NaCl type structure. The distance between P b 2 + and S 2 - ions is 297 pm. What is the volume of unit cell of PbS?, 209.6 × 1 0 - 24 c m 3, 207.8 × 1 0 - 23 c m 3, 22.3 × 1 0 - 23 c m 3, 209.8 × 1 0 - 23 c m 3

MARKS App · Accepted Answer

Edge length of unit cell = 2 r = 2 × 297 pm = 594 × 1 0 - 10 cm Volume of unit cell = a 3 = ( 594 × 1 0 - 10 ) 3 c m = 209.6 × 1 0 - 24 c m 3 .
