Question

An element (atom mass = 100 g/mol) having BCC structure has its cell edge 400 pm. The density of the element is, 2.144 g / c m 3, 5.188 g / c m 3, 7.289 g / c m 3, 10.376 g / c m 3

MARKS App · Accepted Answer

ρ = Z × M w N A × V = 2 × 100 6 × 1 0 23 × ( 400 × 1 0 - 10 ) 3 = 5.188 g / c m 3
